Core Performance Team Update: April 27, 2023

Performance Lab plugin updates are released monthly on the third Monday of the month.

April’s release 2.2.0 includes a few enhancements relating to the creation of standalone plugins. The Fetchpriority module furthermore had its “experimental” flag removed, now that the underlying HTMLHTML HTML is an acronym for Hyper Text Markup Language.

The first step in publishing modules as standalone plugins saw the WebP Uploads plugin published in April. The Fetchpriority plugin is currently awaiting approval from the WordPress plugin team, and Dominant Color Images will follow. An engineering approach to removing these modules from the PL plugin is being discussed.

Progress can be seen in this GitHub repo, which eventually should be transferred to the WordPress organization.

The team continues researching remaining problems with lazy-loading. They have also been finalizing an initial performance profiling analysis of WordPress, which they plan to share with the community, and from which they are planning to identify future actionable items. Other exploration has been taking place on improving option autoloading and also on enhancing the initial automated performance workflow.

Tickets

In addition to Performance Lab, the Performance Team also works on performance-related tickets in core and holds a fortnightly Bug Bash on Wednesdays; check https://make.wordpress.org/meetings/ for current time.

The cadence of the performance bug scrubs has been changed to every 2 weeks, from Wednesday April 26 onwards to ensure issues targeting the next WordPress release are reviewed more frequently.

A blog post for the benefits of prioritizing and measuring performance in 6.2 was released this week as a performance retrospective on the 6.2 release cycle, outlining WordPress 6.2 loads 14-18% faster overall for 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 team is heavily working on further performance tickets prioritized for the upcoming 6.3 release.

WordPress 6.2 contains many performance improvements and analysis demonstrates it is notably faster than 6.1, both on the server-side and the client-side, as seen in early Web Vitals metrics from the lab. After several weeks of different testing methodologies being trialed, we now have an approach that works well for this type of benchmarking (expect a blog post sharing this soon!).

The automated performance testing CI workflow has been committed to core [55459]. We’re successfully getting automated performance data on every commit to core now available in the dashboard here https://www.codevitals.run/project/wordpress.

Core Performance Team Update – September 30, 2022

Performance Lab

Performance Lab plugin updates are released monthly on the third Monday of the month.

September’s release, v.1.5.0, was a small one as the team was focused on WebP work (see below). The only addition was an improvement to the autoloaded options Site Health check.

Proposals and Discussion

Performance Team chats are held weekly on Tuesdays; check https://make.wordpress.org/meetings/ for current time.

The team worked over the last several months to add WebP and multiple MIME support for images for inclusion in 6.1 (see #54086, #54094, and #54097). Per Matt’s post on 11 September, this work will not be included in 6.1 and we are working to identify next steps. The WebP additions were reverted on 19 September.
We have several new Performance Lab modules in the works, including:
- Optimize autoloaded options to track which autoloaded options are actually being used on a site and, based on that, regularly rebuild the list of options to autoload by dynamically modifying the `autoload` column in the database
- Database performance Health Checks to identify the site’s database server version and recommend updating as well as noting issues with MySQLMySQL MySQL is a relational database management system. A database is a structured collection of data where content, configuration and other options are stored. https://www.mysql.com/. tables
- Add `fetchpriority=high` to non-lazy images to set the Largest Contentful Paint (LCP) or first large image on a page in order to improve the page’s LCP
- Background processing infrastructure (part of the currently on hold regenerate existing images work) to build out a new infrastructure for background processing that can be utilized for a variety of future use cases
@aristath’s proposal to add SQLite support to coreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress. could become a Performance Lab module for initial testing

The Team merged several performance-related improvements for 6.1, including adding two new Site Health checks for Persistent Object Caching (#56040) and Audit Full Page Cache (#56041) from the Performance Lab pluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website.
