WordPress Performance Trac Tickets

Performance Lab Plugin (and other Performance Plugins)

  • @joemcgill Chrome 126 went stable last week, which includes support for auto-sizes, so I’d encourage more folks to start testing the Auto-sizes plugin and provide feedback
  • @mukesh27 For PL plugin PR #1298 is ready for review
  • @westonruter I’ve been working on adding integration between Embed Optimizer and Optimization Detective, allowing the collected URL metrics to inform whether an embed should be lazy-loaded and if not (when in the initial viewport) to add preconnect links. This has exposed some limitations with the current implementation so I’ve been refactoring how the tag processor is leveraged which will make it much more powerful for extensions to apply optimizations. Currently still a draft but should be ready for review this week: https://github.com/WordPress/performance/pull/1302
  • @westonruter for Speculative Loading, there’s a PR now to implement support for the search form, but this currently requires a hack which has been reported upstream to Chromium to allow speculative loading prerenders for GET forms: https://github.com/WordPress/performance/pull/1297
  • @westonruter ready for review is another PHPStan PR to apply strict rules: https://github.com/WordPress/performance/pull/1241

Active Priority Projects

Improving the calculation of image size attributes

  • @mukesh27 For accurate sizes, we used a different approach for updating the sizes. The PR #1252 is ready with those changes. If anyone has a moment, please take a look

Optimized Autoloaded Options

  • @joemcgill our only remaining task is to publish the dev note. I saw that @adamsilverstein provided some minor feedback, which @pbearne has already addressed. I think it’s probably read to go

Improved template loading

  • @thekt12 I have addressed feedback from @joemcgill –  https://github.com/WordPress/wordpress-develop/pull/6781. I still need to move this to GB as this is GB first issue
  • @joemcgill one of the things that I’ve been thinking about, related to these types of caches—where we’re trying to add persistence to all sites via the use of transients—is what is the best way to avoid the extra DB query that gets made when you have a transient with a TTL value. It may be worth updating the transient API to allow for autoloading to be specified when setting the transient.

Open Floor

  • @joemcgill reminder about the new project board that we’ve got set up here. I’m curious if anyone is still using the older project boards on a regular basis. If not, I think we can remove them.

Our next chat will be held on Tuesday, June 25, 2024 at 15:00 UTC in the #core-performance channel in Slack.
