WordPress Performance Trac Tickets

Performance Lab Plugin (and other Performance Plugins)

  • @mukesh27 PR that ready for review:
    • PR #1298 – Audit Autoloaded Options Site Health should extend Core’s check if available
  • @joemcgill Also worth noting that Chrome 126 is scheduled to ship today with auto-sizes support turned on, so we should be able to get better testing feedback soon from folks using that feature plugin.

Active Priority Projects

Improving the calculation of image size attributes

  • @mukesh27 has been working on improved image sizes algorithm
    • PRs merged:
      • PR #1250 – Initial implementation of improved image sizes algorithm
    • PRs ready for review:
      • PR #1290 – improved image sizes for left/right alignment
      • PR #1252 – Use correct sizes for small images

Optimized Autoloaded Options

Improved template loading

  • @thekt12 I have raised a new bug #61405 (with a POC that currently breaks some tests ). Same pattern was also observed in WP_Theme_JSON_Data::$theme_json, but I am not sure of the performance impact it will have. PR#6781 will address the remainder of #57789 and #59600 ; estimated to give at least 3% improvement.

Open Floor

Our next chat will be held on Tuesday, June 18, 2024 at 15:00 UTC in the #core-performance channel in Slack.
