  • @swissspidy provided his update in the comments of the agenda for i18n performance:
    • After the initial i18n performance analysis blog post we want to continue testing the Ginger MO solution, submit it to the plugin directory ASAP (long queue!), and promote it in the Performance Lab plugin.
    • It was suggested to find a more descriptive plugin name than “Ginger MO” — please leave your feedback here
    • Will also ask people & hosts at WCUS to test it in their environments.
  • @joemcgill I’ve been doing some profiling of WP 6.3 with a goal of looking for opportunities to improve the template loading process, and am curious about some of the effort that’s gone into making the underlying caching of theme_json data more persistent.  I know that in 6.3 we decided not to use a transient for this data, but would be interested in more context and if there are opportunities to look into this further in 6.4 @oandregal and @flixos90 would probably have the most context here.

Creating Standalone Plugins

Link to GitHub overview issue

Contributors: @flixos90 @mukesh27 @10upsimon

  • @10upsimon I’ve been working on an ongoing POC for managing standalone performance plug-ins from the performance plug-ins settings screen, I’m almost at a point where I’m happy to share the code engineered this far for further team input.
  • It’s involved introduction of a class structure and thus some minor additions to engineering infrastructure too (class auto loading etc).
  • It also involves the addition of what I believe to be the first asset (js/css) of the plug-in and so I’m thinking of also working on a rough POC implementation for asset build handling as well.
