Discussion

  • @spacedmonkey working on #57496, #58001 and #59592 all of which could use more eyes on them
  • @mukesh27 The initial context related issue for blocks has been fixed for 6.8 and committed! https://core.trac.wordpress.org/changeset/59662
  • @flixos90 looking for reviews for https://github.com/WordPress/wordpress-develop/pull/7860, which is for #62503. Since this is a new performance feature, it would be great to get eyes soon – we probably would want to merge this sooner than later to have ample time for testing
  • @joemcgill left an update on #62126 – TL;DR, this one I was reviewing that needs to be picked up and the original reporter hasn’t responded so it’s likely a puntpunt Contributors sometimes use the verb "punt" when talking about a ticket. This means it is being pushed out to a future release. This typically occurs for lower priority tickets near the end of the release cycle that don't "make the cut." In this is colloquial usage of the word, it means to delay or equivocate. (It also describes a play in American football where a team essentially passes up on an opportunity, hoping to put themselves in a better position later to try again.) unless someone else wants to give it a look.
  • @mukesh27 For accurate sizes, opened two PRs, #1795 and #1818, and currently discussing with @joemcgill the best path forward to address the issue for nested blocks. Received some valuable feedback from Joe, which is being implemented

Discussion

  • Bug scrub cadence proposal from @flixos90
    • Bug scrub meetings can be inefficient because the people who need to weigh in on tickets are usually not there. So they sometimes end up mostly as a “monologue”.
    • There’s also the overhead of commenting on the ticketticket Created for both bug reports and feature development on the bug tracker. but also sharing what happens in SlackSlack Slack is a Collaborative Group Chat Platform https://slack.com/. The WordPress community has its own Slack Channel at https://make.wordpress.org/chat/., which makes scrubbing the bugs slower.
    • Scheduled 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. scrubs are important also for the fact that otherwise there’s a chance nobody will do it.
    • We could consider a format where we have regular bug scrubs, but it’s always one person doing it (rotating per meeting). They would always share a report on Slack when they start and then go over the tickets on their own and comment on each ticket with whatever update they think makes sense (checking in with reporter or PR author, changing milestone, changing priority, …).
  • After discussion, it has been agreed that the cadence of these meetings will remain fortnightly, and will be led by one person
    • The recommended process has been captured in this document which we invite people to review and comment
    • The rotation of bug scrub leads can be found in this spreadsheet – we welcome volunteers to help here

WordPress 6.7 Performance Improvements

This post is the latest in a series of updates focused on the performance improvements of major releases (see 6.6, 6.5, 6.4, 6.3, and 6.2).

WordPress 6.7, “Rollins” is the last major version of WordPress released in 2024. This release delivers important performance updates, including faster pattern loading, optimized previews in the data views component, improved PHPPHP The web scripting language in which WordPress is primarily architected. WordPress requires PHP 7.4 or higher 8+ support and removal of deprecated code, auto sizes for lazy-loaded images, and more efficient 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.) processing in the HTMLHTML HyperText Markup Language. The semantic scripting language primarily used for outputting content in web browsers. 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..

Explore the WordPress 6.7 Field Guide. Learn about the changes in this release with detailed developer notes.

Further details on the methodology behind these measurements are provided later in this article, along with an explanation of possible regressionregression A software bug that breaks or degrades something that previously worked. Regressions are often treated as critical bugs or blockers. Recent regressions may be given higher priorities. A "3.6 regression" would be a bug in 3.6 that worked as intended in 3.5. sources.

Key improvements

Media: Auto sizes for lazy loaded images

In #61847,  support was added for sizes=”auto” for lazy-loaded images. This feature, which was recently added to the HTML specification, allows the  browser to use the rendered layout width of the image when selecting a source from the srcset list, since lazy loaded images don’t load until after the layout is known. It maintains backward compatibility while boosting performance, particularly for responsive and dynamic layouts. Explore the details in the official dev note.

Media: Caching _wp_image_editor_choose results for improved performance

In #61532, WordPress now caches the results of _wp_image_editor_choose, storing the WP_Image_Editor implementation that supports queried options. This avoids redundant and costly compatibility checks, such as multiple calls to WP_Image_Editor_Imagick::supports_mime_type(), often triggered during tasks like setting up wp_plupload_default_settings(). The cache, stored for one day, speeds up editor loading times and introduces a new global caching group, image_editor, to manage future optimizations for image editor performance.

Media: Improve speed of AVIF image generation

In #61758, the change results in the AVIF encoder working faster by raising heic:speed to 7 from the default of 5. AVIF generation time is reduced by up to 20% with minimal impact on image size.

Editor: New 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. type registration APIs to improve performance

In #62002, new block type registration APIs were introduced, offering a more efficient way to manage block metadata and improve performance across the board. These APIs allow developers to register blocks more flexibly, reducing server-side processing and enhancing editor load times. With these changes, WordPress lays the groundwork for faster, more scalable block-based experiences while maintaining backward compatibility. Explore the details in the official dev note.

Editor: Caching Global Styles for Blocks

In #59595, profiling WordPress 6.4 revealed that the WP_Theme_JSON::compute_style_properties method could account for 6-11% of server time during page generation. To address this, the editor now caches the generated CSSCSS Cascading Style Sheets. for block nodes derived from merged Theme JSONJSON JSON, or JavaScript Object Notation, is a minimal, readable format for structuring data. It is used primarily to transmit data between a server and web application, as an alternative to XML. data. By saving the computed styles in a transient, WordPress avoids repeated and resource-intensive operations, significantly improving performance and reducing server load. This change is a key optimization for sites leveraging block themes and theme.json.

Themes: Improve performance of applying background image styles in theme.json.

In #61858, the cost of using WP_Theme_JSON::get_block_nodes() for this in its original shape was high enough to lead to a performance regression. Therefore this changeset introduces a new option on the method that allows to bypass all logic except for retrieving the node paths, which is much faster and everything that this functionality needs.

Miscellaneous Editor improvements:

In addition to the previously listed editor improvements, this release includes the following list of changes that improves the editor experience itself:

Additional performance focused changes

In total, there were 23 performance related improvements included in this release, split evenly between new enhancements (12) and 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. fixes (11).

Performance metrics

In our analysis, block themes (Twenty Twenty-Four was tested) experienced a modest regression in performance. The median Largest Contentful Pain (LCP) time increased by ~6ms or ~3.5% in tests, and the median Time To First Byte (TTFB) shows a 2ms (2%) regression.

Classic themes show a slight improvement (Twenty Twenty-One was tested). The median Largest Contentful Pain (LCP) and Time To First Byte (TTFB) time shows a slight 0.2ms or 0.2% improvement in tests.

How release performance is measured

The performance measurements used for the overview are based on benchmarks conducted using an automated workflow on GitHubGitHub GitHub is a website that offers online implementation of git repositories that can easily be shared, copied and modified by other developers. Public repositories are free to host, private repositories require a paid subscription. GitHub introduced the concept of the ‘pull request’ where code changes done in branches by contributors can be reviewed and discussed before being merged be the repository owner. https://github.com/ action runners. Benchmarks were taken from the homepage of the Twenty Twenty-one, Twenty Twenty-three, and Twenty Twenty-four themes, comparing WordPress 6.7 with WordPress 6.6.2 (the latest version of WP 6.6 available when 6.7 was released).

Performance metrics were collected from 100 runs for both CoreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress.

Benchmark Data

Follow up from this release

WordPress 6.7 shows a regression in performance. While some overhead typically accompanies new features, these declines point to areas where the performance team continues to investigate where these regressions came from and how they can be addressed in the upcoming releases.

Each release, the Performance Team looks for opportunities to improve the performance of WordPress for the following releases, which includes identifying ways we can improve the tooling and processes we use to support the performance practice. For example, we’re collecting opportunities to improve our performance testing in this GitHub issue

Performance Lab – the plugin(s) we use to test out new performance features for core – continues to add new features such as Image Prioritizer , Embed Optimizer, Speculative Loading, Performant Translations, Modern Image Formats, Enhanced Responsive Images, and Web Worker Offloading.

You can also follow progress on other performance-related work being planned for the WordPress 6.8 release in Trac. A full list of the Performance Team’s priorities for the year is available on the 2024 Roadmap page. Additionally, the 2025 Roadmap will be published early in Q1 2025 in the team’s handbook. Come join us in making WordPress as performant as possible.

Hallway Hangout: Performance End of Year Review 2024

Following up on the prior performance related Hallway Hangout: Performance End of Year Review 2023 in December, @flixos90 @joemcgill and @clarkeemily co-hosted a hallway hangout to review the work and impact of the performance team in 2024, and look ahead to performance improvements in WordPress for 2025.

The Hallway Hangout took place at 2024-12-17 16:00 UTC and the Google Meet link was shared in the #core-performance SlackSlack Slack is a Collaborative Group Chat Platform https://slack.com/. The WordPress community has its own Slack Channel at https://make.wordpress.org/chat/. channel before starting.

At a high level, we went through:

  • Review of WordPress performance improvements throughout 2024
  • Breaking down CoreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress. Web Vitals metrics (November 2023 – November 2024) resulting in CWV passing rates increasing by 6.07% on mobile and 5.92% on desktop
  • WordPress 2024 releases overview (6.5, 6.6 and 6.7) were discussed individually
  • The impact of specific metrics for major features released in 2024 (Enhanced translations engine, Interactivity 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. and image sizes=auto)
  • A look ahead to 2025 plans

As a reminder, hallway hangouts are meant to be casual and collaborative so come prepared with a kind, curious mind along with any questions or items you want to discuss around this important area of the project, especially since the agenda is intentionally loose to allow for it.

Notes

@flixos90 presented the WordPress Performance 2024 CWV Impact Retrospective slide deck, thank you very much for pulling that together Felix.

    TTFB Improvements

    @pbearne @flixos90 @joemcgill @westonruter and @adamsilverstein were discussing TTFB passing rates and why the rest of the web has higher rates than WordPress due to that metric. Discussions were held around filtering sites to the top 10k or 100k of sites to re-evaluate passing rates without the bottom end of sites that are not set up correctly. When WordPress is configured correctly, passing rates are much higher, so it was suggested that outreach in the ecosystem may be encouraged to facilitate better hosting environments. The new Core #core-performance-hosting channel will help facilitate these conversations.

    The team went on to discuss file caching and the potential to introduce a file caching API in core. It was agreed this would be a very large effort and would need contribution from multiple teams. We would need to revisit the original decision from WordPress to keep file caching in pluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party territory as opposed to within Core. We would also need significant investigation into the large number of WordPress sites where static caching is not something their site can support. 

    Auto Sizes Metric

    The team discussed whether the auto-sizes metric in the slides was the top 70th percentile (it is). 

    Plans for 2025

    There are still some projects ongoing from 2024 to land, speculative loading now has a TracTrac An open source project by Edgewall Software that serves as a bug tracker and project management tool for WordPress. ticketticket Created for both bug reports and feature development on the bug tracker.. Next steps on responsive image sizes improvements are in progress. The accurate image sizes work. The last piece of dominant colour is going in too! 

    Accurate Image sizes

    The project @joemcgill and @mukesh27 are focusing on will have significant releases this week, around having more detail on the layout of the page and how we can make more informed choices about accurate image sizes. This essentially takes the layout information of image blocks and cover blocks, but also the constraints of the container around it (group blocks) so we can put limits on the size we expect to show things at. The discussion continued around how we can accurately set image sizes in WordPress. 

    Optimization Detective

    @westonruter is continuing to work on the optimisation detective plugin which will include prioritisation of background images defined in external file sheets – this will dramatically improve LCP. In the new year he will be continuing to refine the foundation and use cases to hopefully get more adoption and propose for core. @flixos90 reminded the team that this is a great plugin example which improves how well other performance optimisations are applied. It’s important to improve what we already have in core, and this plugin helps that.

    Props to @joemcgill for proof reading and @flixos90 for the excellent presentation.
