WordPress Performance Trac Tickets

  • There are currently 16 performance issues in 6.7
  • @pbearne I need input on this ticketticket Created for both bug reports and feature development on the bug tracker. as I made opinionated changes as to which option should not be autoloaded #61103
    • @joemcgill I plan on digging into that PR to give you feedback, but am going to be out on holiday for a bit. If anyone else has time to look at this in the mean time, please do so.
    • @mukesh27 I will take a look this week
    • @joemcgill One thing that will be good to understand, is that if we aren’t autoloading options that are only needed in the adminadmin (and super admin), how do we make sure the editor experience isn’t negatively affected. I think you’re already planning on priming all of those options in the admin, but would be good to get some performance measurements of the before/after of both the front end and admin.
    • @pbearne I have a patchpatch A special text file that describes changes to code, by identifying the files and lines which are added, removed, and altered. It may also be referred to as a diff. A patch can be applied to a codebase for testing. to load the admin options in back on wp_int

Performance Lab Plugin (and other Performance Plugins)

  • @mukesh27 I have been working on PRs that ready for review:
    • Performance Lab plugin:
      • PR #1374 – Autoloaded Options Health Check: Disabled options reappear in Site Health after external update
    • Modern Image Formats plugin:
      • PR #1354 – Picture element: The accurate sizes improvement for images not working
  • @westonruter It seems like we’re getting increasing reports of issues with image generation in Modern Image Formats
    • In GitHub and support forums
    • @westonruter Might be related to the issue of AVIF generation taking a very long time sometimes?
    • @joemcgill Ah, I do remember cases a long time ago where image generation could take longer than the max PHPPHP The web scripting language in which WordPress is primarily architected. WordPress requires PHP 5.6.20 or higher timeout on some hosts and result in the attachment data being created in the DB while the actual image generation failed. I wonder if something like that is happening?
    • @westonruter That’s being discussed here: https://github.com/WordPress/performance/issues/371
    • @adamsilverstein this could also be a support detection issue, (where format support for AVIF gives a false negative or positive), interesting they say it falls back to WebP
    • @westonruter I wonder if the AVIF generation should be moved a background process? Use the JPEG immediately upon upload and then use the AVIF once it is available
    • @adamsilverstein we already have a way of generating images in multiple passes, but it needs to be able to process one image completely before the timeout
    • @joemcgill That’s a good idea. There is prior art for generating missing intermediate sizes that could be referenced.
    • @pbearne Idea: we need a long process control for wp-admin that can be used for any task that takes a long time (images gen, post delete, etc.)
    • @adamsilverstein https://github.com/WordPress/performance/issues/490 was part of that previous effort, there is also a trac ticket
    • @westonruter I thought that was primarily for regenerating the entire media library
    • @adamsilverstein yes, but part of that was the ability to regenerate images in i the background #6814 16 year old ticket
    • @joemcgill It’s not totally accurate anymore, after #40439
    • @adamsilverstein true, we partially solved the issue with that, as long as the user agent remains present to trigger the retries
    • @joemcgill I’ve played with using WP_Cron for this a looooooong time ago, but that can cause failures to affect end-user front-end requests, which we’d want to avoid

Active Priority Projects

Improving the calculation of image size attributes

  • @mukesh27 For Improving the calculation of image size attributes i have been working on:
    • PR #1382 – Update wp_calculate_image_sizes to Reflect Changes in sizes attribute
    • Issue #1389 – Accurate sizes improvement didn’t account for the disable filterFilter Filters are one of the two types of Hooks https://codex.wordpress.org/Plugin_API/Hooks. They provide a way for functions to modify data of other functions. They are the counterpart to Actions. Unlike Actions, filters are meant to work in an isolated manner, and should never have side effects such as affecting global variables and output. for sizes
    • @joemcgill I’m reviewing those this morning

Plugin Check

Open Floor

  • WordPress 6.6 performance analysis
    • @adamsilverstein Yes… I have been working on a post for 6.6 performance changes and will share a draft here for feedback soon!
    • one challenge has been identifying the source of the slight regressions we see in 6.6 (the numbers haven’t changed much since I shared results here for an RCrelease candidate One of the final stages in the version release cycle, this version signals the potential to be a final release to the public. Also see alpha (beta). a few weeks ago)
    • part of the challenges is tracking changes that originate in the GutenbergGutenberg The Gutenberg project is the new Editor Interface for WordPress. The editor improves the process and experience of creating new content, making writing rich content much simpler. It uses ‘blocks’ to add richness rather than shortcodes, custom HTML etc. https://wordpress.org/gutenberg/ project and are then merged over to coreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress.. our automated tests haven’t highlighted issues, nor are the Gutenberg performance tests
    • some ideas: it might be because the regressions are very small and spread out over a number of commits, or it might be related to the difference in how we are doing automated tests. in case, it points to an area we can improve
    • @joemcgill Agreed. There are a number of improvements that we could make to our CI infrastructure in both the GB repo and in Core that would help. We’ve already got https://github.com/WordPress/performance/issues/1380 as a place to discuss a set of improvements we want to focus on next. I’d love to see more discussion there so we can define and prioritize some next steps.
    • One of the questions that I still have is whether the benchmarks that we have been taking at the end of each release are providing us with useful info, or if they are obscuring what is really happening in the field.  @adamsilverstein I’m curious if we could get some HTTPArchive data after 6.6 has been out a while to see if our lab benchmarks relate to real user data or not.
    • @adamsilverstein that is a good point, I’m happy to work on that. we should have enough data in a few months.
    • some performance improvements we are adding will really only become apparent in the field data, and our automated testing can’t really measure those

WordPress Performance Trac Tickets

  • @joemcgill For visibility: on Friday, I reverted r58334 due to a late reported bugbug A bug is an error or unexpected result. Performance improvements, code optimization, and are considered enhancements, not defects. After feature freeze, only bugs are dealt with, with regressions (adverse changes from the previous version) being the highest priority. related to the caching global styles for blocks. This was done as part of #59595. I have a PR that I need to refresh that fixes the issue and reinstates the cache, which I hope to have included in 6.6.1.
  • There are currently 12 performance issues in 6.7 which will be reviewed in tomorrow’s bug scrub

Performance Lab Plugin (and other Performance Plugins)

  • @mukesh27 I have also opened an issue for the Picture element: The accurate sizes improvement for images not working #1349. The new changes from the Enhanced Responsive Images (formerly known as auto-sizes) plugin are not working
    • @westonruter let’s prioritize fixing those and push out short-cycle standalone releases
    • @mukesh27 confirmed it’s Modern Image formats plugin causing the bug and will share more details on issue

Active Priority Projects

Improving the calculation of image size attributes

  • @joemcgill now that we’ve released the first version of Auto-sizes Enhanced Responsive Images that includes those improvements, I think @mukesh27 and I will need to update the overview issue with the main goals for the next priority features. At the same time, we’ll continually iterate on issues that come up during testing.

Improved template loading

  • @joemcgill There were a couple of remaining tasks open on the Improved template loading epic, but at this point, we’ve accomplished the majority of what was originally planned and the remaining items really are iterative improvements to the WP_Theme_JSON system that really could be tracked as part of ongoing CoreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress. work, or as a collaborative issue in the GutenbergGutenberg The Gutenberg project is the new Editor Interface for WordPress. The editor improves the process and experience of creating new content, making writing rich content much simpler. It uses ‘blocks’ to add richness rather than shortcodes, custom HTML etc. https://wordpress.org/gutenberg/ repo, so I’m going to close up the related tickets and close that issue.
  • This section will be dropped from the agenda moving forwards

Plugin Check

Open Floor

  • @swissspidy I opened a proposal a while ago for a new PL plugin: https://github.com/WordPress/performance/issues/1324 The idea is to take data collected by Optimization Detective and display them in a nice little dashboard. Not sure yet how useful that would be, but thought I’d share it 🙂
    • @joemcgill I love this idea and wonder if there is an opportunity to surface other kinds of performance data on that dashboard, like CWV scores if available, etc. Though I really like the different use cases we’re finding for the Optimization Detective APIAPI An API or Application Programming Interface is a software intermediary that allows programs to interact with each other and share data in limited, clearly defined ways.. “CWV scores if available” meaning from the CrUX API
      • @westonruter I suppose to compare with the CWV metrics from actual visitors as measured by Optimization Detective?
    • @westonruter Yeah, actually storing the CWV metrics in the URLURL A specific web address of a website or web page on the Internet, such as a website’s URL www.wordpress.org Metrics custom post typeCustom Post Type WordPress can hold and display many different types of content. A single item of such a content is generally called a post, although post is also a specific post type. Custom Post Types gives your site the ability to have templated posts, to simplify the concept. would be a key part of this. Currently we only store which element was the LCP, not what the LCP metric is.
    • @joemcgill Unless we’re collecting metrics from every visit, I think we’d need to somehow be clear about how those CWV metrics are representative of real users, and not a full picture.
    • @westonruter Yeah. It would be a sampling, for sure. But so is CrUX. Although surely CrUX sampling would be higher, assuming you get enough traffic to qualify
    • @joemcgill It is, but CrUX is a larger sample size than what we’re collecting with OD. The real value is that this would allow sites to get URL level data which can be more difficult for site owners to get from CrUX
    • @swissspidy There was also a proposal to use a separate storage mechanism (e.g. a custom table or CPT) that allows storing the data for more than 30 days
    • @swissspidy Precisely. And also without waiting for next month’s data to arrive etc. You could more quickly see the performance impact of changes made to the site.
    • @joemcgill Rather than making this a separate plugin, I really think we should consider adding this type of data to Performance Lab and integrate OD when available (or bundle the API into that plugin too). Now that all of our Performance features are unbundled into standalone plugins, I think there’s an opportunity for PL to add more value as a tool for collecting and surfacing performance metrics and opportunities for improvement to site owners.
  • @swissspidy Another quick update from my side: I had some very productive discussions with some Gutenberg folks about client-side media processing and they shared some valuable feedback about separation of concerns. I am currently refactoring my Media Experiments plugin based on that feedback, hoping to have something that can be merged into Gutenberg afterwards. The tracking issue on the Gutenberg repo is this one: https://github.com/WordPress/gutenberg/issues/61447

WordPress Performance Trac Tickets

Performance Lab Plugin (and other Performance Plugins)

  • @westonruter For Embed Optimizer, this PR will be ready for review this morning. I just need to add the description to detail the changes: https://github.com/WordPress/performance/pull/1302
    • This includes fundamental enhancements to Optimization Detective to make it much more powerful to be able to make optimizations to a document (e.g. what Embed Optimizer requires)
  • @westonruter I think the plugin with the most need is Modern Image Formats as there are a couple bugs needing to be fixed: https://github.com/WordPress/performance/milestone/59
  • @mukesh27 the updated sizes feature from auto-sizes is ready for this release, some final PRs ready for review:
    • PR #1335 – Plugin rename
    • PR #1329 – Merge feature branchbranch A directory in Subversion. WordPress uses branches to store the latest development code for each major release (3.9, 4.0, etc.). Branches are then updated with code for any minor releases of that branch. Sometimes, a major version of WordPress and its minor versions are collectively referred to as a "branch", such as "the 4.0 branch". to trunktrunk A directory in Subversion containing the latest development code in preparation for the next major release cycle. If you are running "trunk", then you are on the latest revision.
  • @joemcgill there’s also a proposed name change for the Auto-Sizes plugin

Active Priority Projects

Improving the calculation of image size attributes

  • Discussed above

Improved template loading

  • @joemcgill The template loading work is mainly wrapped up in 6.6. There are a few minor follow-up issues that I think we’ll continue to track but I’ll work on summarizing next steps and closing up those GH issues.
    • The two things that are on my mind in the short term are:
      • Supporting the Plugin Check project as the Plugin Review team are working to get it integrated into their systems.
      • Improving our performance metrics for both CoreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress. and GB.

Plugin Check

  • @joemcgill For Plugin Check, I’d like to get more eyes on this conversation., which may end up being a requirement for them to do the integration

Open Floor

  • @mukesh27 Do we have any open issue for Improving our performance metrics for both Core and GB 
  • @joemcgill raised that @swissspidy mentioned one last week that included both misc improvements and shared performance tooling and asked about whether we should separate these issues https://github.com/WordPress/performance/issues/1093
    • I do think it would serve us well to put some focus on this early in the 6.7 cycle so we can more easily pinpoint which commits have server timing performance implications. That’s been a big challenge the past 2 releases. (In the GB repo specifically)
  • @pbearne I am thinking of suggesting that WP has an infrastructure release where we update/re-organize the PHPUnit tests etc. as without core committers actively making the changes it will never get done. The performance testing could be part of this
    • @joemcgill I would suggest proposing the infrastructure changes you have in mind and whether those become a release focus or not, could be secondary.

Also see regression. for https://github.com/WordPress/gutenberg/pull/62794/files ( had some issues with unit test, will connect with Joe to help here)

Open Floor

  • @adamsilverstein wanted to call attention to this post – https://make.wordpress.org/hosting/2024/06/19/the-image-revolution-avif-and-webp/ from @javiercasares and the hosting team about how hosts can enable AVIF / modern image support for their customers – and why they should consider doing it!
    • Only something like 30% of sites are on hosts that currently support AVIF so this is great to see
  • @pbearne We have a question on autoload and the setting APIAPI An API or Application Programming Interface is a software intermediary that allows programs to interact with each other and share data in limited, clearly defined ways.. “Is there a way to set an option to not autoload if I am using Settings API?” I created a ticketticket Created for both bug reports and feature development on the bug tracker. for this #61522 – Is this something we should look at?
  • @pbearne And a second opinion on adding a blockBlock Block is the abstract term used to describe units of markup that, composed together, form the content or layout of a webpage using the WordPress editor. The idea combines concepts of what in the past may have achieved with shortcodes, custom HTML, and embed discovery into a single consistent API and user experience. option load to wp-adminadmin (and super admin)
    https://github.com/WordPress/wordpress-develop/commit/75d83b656609ad6092146fb7183b58beb859feae Is this the right action? Should we have one for Front-end?

WordPress Performance Trac Tickets

  • Last 2 performance tickets for 6.6 #59595 (merged) and #59600 (punted)

Performance Lab Plugin (and other Performance Plugins)

  • @thelovekesh added testing steps on https://github.com/WordPress/performance/pull/1247 which is ongoing PR for adding Web Worker Offloading plugin. As per last discussion on merging it in trunktrunk A directory in Subversion containing the latest development code in preparation for the next major release cycle. If you are running "trunk", then you are on the latest revision., this PR is ready for that
  • @westonruter hopes to pick up Web Worker Offloading next week
  • @mukesh27 the Extend core’s Autoloaded Options Site Health test if present (in WP 6.6) is merged
    @mukesh27 opened a couple issues related to Modern Images Formats and the implementation of the picture element. Those are up for grabs for anyone wanting to contribute
  • @westonruter Related to that, I found a downside to using the picture element in the first place, in that it is not currently possible to add fetchpriority=high preload links for picture elements since the link tagtag A directory in Subversion. WordPress uses tags to store a single snapshot of a version (3.6, 3.6.1, etc.), the common convention of tags in version control systems. (Not to be confused with post tags.) doesn’t replicate all of the picture element’s sourcing features: https://github.com/WordPress/performance/issues/1312
    • @joemcgill Does adding fetchpriority directly to the image not work in this case?
    • @westonruter Yes that does, but the problem occurs when there are varying LCP elements for different breakpoints. So Image Prioritizer will need to explicitly avoid adding a preload link when the LCP element is a picture.
    • @joemcgill I would think that picture would make that easier, because each source would have it’s own media attribute
    • @westonruter Otherwise, it adds preload links for the LCP element in each breakpoint. The problem with the picture element is the type not the media.
      • Unless, would a browser skip requesting a preload link for an image when it has a type that is not supported? I didn’t think it did. But I’ll need to check that
  • @westonruter Related to Image Prioritizer, I’ve opened several other issues for enhancementenhancement Enhancements are simple improvements to WordPress, such as the addition of a hook, a new feature, or an improvement to an existing feature. ideas on top of Optimization Detective.

Active Priority Projects

Improving the calculation of image size attributes

Optimized Autoloaded Options

  • The dev notedev note Each important change in WordPress Core is documented in a developers note, (usually called dev note). Good dev notes generally include a description of the change, the decision that led to this change, and a description of how developers are supposed to work with that change. Dev notes are published on Make/Core blog during the beta phase of WordPress release cycle. Publishing dev notes is particularly important when plugin/theme authors and WordPress developers need to be aware of those changes.In general, all dev notes are compiled into a Field Guide at the beginning of the release candidate phase. has now been psoted https://make.wordpress.org/core/2024/06/18/options-api-disabling-autoload-for-large-options/

Improved template loading

  • @thekt12 I am working on review from @joemcgill here –
    https://github.com/WordPress/gutenberg/pull/62794/files
  • @joemcgill #59600 and #57789 have a lot of overlap and the former is mostly irrelevant at this point. We fixed the biggest problem #59600 with blockBlock Block is the abstract term used to describe units of markup that, composed together, form the content or layout of a webpage using the WordPress editor. The idea combines concepts of what in the past may have achieved with shortcodes, custom HTML, and embed discovery into a single consistent API and user experience. patterns, but still have some things we wanted to progress in 6.7 for the WP_Theme_JSON system. However, the maintenance of that system between the GB repo on the CoreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress. repo has made executing and testing changes reliably pretty challenging. I opened this issue to discuss how we can improve this process going forward. I’d be happy for folks here to give feedback.
    • In terms of our tracking issue, I’ll post an update in light of the final 6.6 changes we were able to make and update any remaining tasks we want to pursue.

Open Floor

  • @joemcgill FYI: there’s a new channel, #pluginreview-plugincheck to have discussions related to maintaining the Plugin Check plugin that we helped build.
    • @thekt12 mentioned most PRs show errors
    • @joemcgill I’ve seen that on occasion as well, but not causing any merge checks to fail, and not consistently with the same message. Could be flaky e2e tests. 
  • @mukesh27 As the Performance Lab plugin has added support for WebP, AVIF, and Picture elements, what is the tentative WordPress version we are targeting for merging these features?
    • @joemcgill WP already supports uploading those versions, and gives site owners the ability to convert uploaded files to those formats using a filterFilter Filters are one of the two types of Hooks https://codex.wordpress.org/Plugin_API/Hooks. They provide a way for functions to modify data of other functions. They are the counterpart to Actions. Unlike Actions, filters are meant to work in an isolated manner, and should never have side effects such as affecting global variables and output., but there are currently no plans to make either the “default” format that is used for the intermediate sizes that WP creates.
    • @westonruter And merging picture element support will require a lot of testing and there will certainly be many theme and plugin compatibility issues
    • @joemcgill #55443 is probably the best ticketticket Created for both bug reports and feature development on the bug tracker. to revisit for this

Our next chat will be held on Tuesday, July 2, 2024 at 15:00 UTC in the #core-performance channel in Slack.
