Performance Chat Summary: 16 June 2026
The full chat log is available beginning here on Slack.
WordPress Performance Trac tickets
- @westonruter shared the current performance-focused Trac report and highlighted #65215.
- @westonruter noted that the ticket is likely close to being merged and just needs another review.
- @mukesh27 asked whether there are any high-priority tickets the team should focus on for WordPress 7.1.
- @westonruter identified View Transitions on the frontend and Enhanced Responsive Images as two areas that stand out for 7.1. and noted that both already have feature plugins and need further iteration before they are ready for a Core merge proposal.
- @nickchomey shared plans to open a Core Trac ticket proposing a libvips-based image editor for WordPress Core. @nickchomey argued that libvips offers significant CPU and memory advantages over Imagick and could be particularly valuable alongside the planned client-side vips-based image processing work expected for 7.1.
- @westonruter agreed that Core support would likely be necessary before hosting providers prioritize adoption, though adoption would likely be gradual. @mukesh27 suggested creating a Core Trac ticket so discussion and feedback could be tracked in a central location. @nickchomey confirmed that a ticket was about to be published.
Performance Lab Plugin (and other performance plugins)
- @mukesh27 shared that work has started on Gallery block support for Enhanced Responsive Images Plugin in PR #2534, with additional PRs planned on a case-by-case basis.
- @westonruter confirmed that @mukesh27 is working on tests for Enhanced Responsive Images.
- @westonruter also mentioned Optimization Detective as another important area to continue moving forward.
- @westonruter noted that a new release of the Performance plugins is needed.
- @westonruter shared that most recent work has focused on infrastructure maintenance with environments, testing, and minimum version bumps, so there is not a whole lot ready to release.
- @westonruter noted that Performance Lab and View Transitions currently appear to have merged PRs ready to go.
- @b1ink0 noted that there are many PRs currently in review across the project milestones.
- @westonruter suggested getting more PRs reviewed and merged and proposed planning for a Thursday release with whatever changes are merged by then.
- @nickchomey shared that work is nearly complete on a PR for CSS Gradient-only Placeholder Images related to issue #2519 and asked whether it might get some eyes on it soon or if priorities are elsewhere for the near future. @westonruter replied that the team should be able to take a look.
- @b1ink0 shared that the “Add support for chronological and pagination transitions” PR #2336 has been pending for a long time and added a comment regarding how the project should proceed with the implementation of the user-facing options.
Our next chat will be held on Tuesday, June 30, 2026 at 16:00 UTC in the #core-performance channel in Slack.
