WordPress Performance Trac Tickets

• There are currently 8 performance issues in 6.7 (bugs)
• Will be discussed in tomorrow’s 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. scrub

Performance Lab Plugin (and other Performance Plugins)

• Performance Lab plugin and the following performance plugins:
  • Enhanced Responsive Images
  • Embed Optimizer
  • Image Prioritizer
  • Image Placeholders
  • Modern Image Formats
  • Optimization Detective (Developer Preview)
  • Performant Translations
  • Speculative Loading
  • Web Worker Offloading

• @clarkeemily there are 12 issues currently ‘In Progress’ from our Performance GitHub board, and also 9 issues in ‘To Do’
  • There are several ‘Good First Issues‘ available for anyone interested in contributing alongside @adamsilverstein
• @mukesh27 For the Modern Image Formats I opened Modern Image Formats: Sub-sizes image didn’t add original image extension issue. @adamsilverstein when you have moment could you please verify the expected behaviour.
• @westonruter There are a few open PRs for Optimization Detective which I’m continuing to iterate on. I plan for these to be ready for review starting today.
• @joemcgill Just wanted to share some encouraging initial CrUX results from the auto-sizes work that @flixos90 was able to gather on https://github.com/WordPress/performance/issues/1186 based on folks who are using the Enhanced Responsive Images plugin.
  • “Worth highlighting: At the 70th percentile, we see a reduction of over 40% on desktop and almost 60% on mobile in terms of wasted pixels and wasted bytes. I also ran a modified version of the query only to get the LCP difference for the similar intersection of sites, and that looks great too, with +8.2% on desktop and +6.2% on mobile (the overall LCP diff in that time for all WordPress sites was only ~+1%, per https://cwvtech.report).”
• @joemcgill This is encouraging, and will be worth keeping an eye on once 6.7 is released, given that we’ve added auto-sizes via #61847

Active Priority Projects

Investigate INP Improvements

• No updates this week

Improving the calculation of image size attributes

• @mukesh27 Regarding the improvements to the calculation, the CoreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress. ticketticket Created for both bug reports and feature development on the bug tracker. #62046, I’ve opened PR #7522, which includes unit tests. The tests have passed, so could @joemcgill please take a look when you have a moment?
  • @joemcgill planning to take a deeper look into #62046 later this week

Enable Client Side Modern Image Generation

• No updates this week

Enhance Onboarding Experience of Performance Lab Plugin

• @flixos90 This already predated last week’s meeting, but I don’t think I shared it here: In https://github.com/WordPress/performance/issues/1032#issuecomment-2384151984 I summarized some of the responses for the onboarding feedback form so far.
  • I think the biggest priority based on the onboarding feedback is to make the feature/plugin activation work via AJAX. Because right now it results in a fresh page load, it means quickly activating multiple features is unnecessarily slow. It can sometimes even lead to weird errors if users click multiple buttons too fast (before the page reloaded)
  • @flixos90 to open an issue for this

Open Floor

• @mukesh27 The WP 6.7 Beta 2 Performance Benchmark Report shows the 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. in 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.

  • The PR https://github.com/WordPress/wordpress-develop/pull/7486 has been reviewed. It explores one approach to address the background image regression, which accounts for a ~4% regression in block themes.
