  • @joemcgill #58196 has a PR that could use another set of eyes, but can probably be committed. However, turns out this does not solve a big performance issue, but instead the parent function needs to be looked into instead.
  • @swissspidy For i18ni18n Internationalization, or the act of writing and preparing code to be fully translatable into other languages. Also see localization. Often written with a lowercase i so it is not confused with a lowercase L or the numeral 1. Often an acquired skill. performance I am nagging people for code reviews again at the moment. Otherwise there hasn’t really been any progress.
  • @joemcgill I was reviewing #55595 earlier today, and noticed that widgetWidget A WordPress Widget is a small block that performs a specific function. You can add these widgets in sidebars also known as widget-ready areas on your web page. WordPress widgets were originally created to provide a simple and easy-to-use way of giving design and structure control of the WordPress theme to the user. registration itself does not really account for much of a performance cost, but rather rendering widgets that can be costly. I think we can likely close that ticketticket Created for both bug reports and feature development on the bug tracker. as `maybelater` but would like a 2nd opinion.
    • Additionally, I noticed that you can already use the `load_default_widgets` filterFilter Filters are one of the two types of Hooks They provide a way for functions to modify data of other functions. They are the counterpart to Actions. Unlike Actions, filters are meant to work in an isolated manner, and should never have side effects such as affecting global variables and output. to keep WP from loading default widgets, but doing so will cause a fatal if you don’t also unhook `wp_widgets_init`, because that function will try to register the default widgets even if they haven’t been loaded. This seems like a 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., although not a critical one.
  • @thekt12 Removing call to build_template_part_block_variations on the fontend showed a decent performance improvement -> Additionally we did identify two more palaces where the same improvement could be made. Currently I am addressing PR review comments.

  • @westonruter Pull request for applying the image optimizations is in review and nearing merge (to the feature branchbranch A directory in Subversion. WordPress uses branches to store the latest development code for each major release (3.9, 4.0, etc.). Branches are then updated with code for any minor releases of that branch. Sometimes, a major version of WordPress and its minor versions are collectively referred to as a "branch", such as "the 4.0 branch".)
    • I also have sub-PR opened which makes breadcrumb processing more reliable. (In other words, an XPath for a given image that needs optimization.) Also ready for review.
    • Now that the feature is fully functional I’m going to add test coverage (which I neglected before getting a working prototype in place).
    • I also want to extend the existing logic to also handle CSS background images, whereas currently only img elements are optimized.
    • I’ve also started filing issues under the module’s label for areas where others can contribute.
  • @joemcgill Still working on a proposal for improving the default sizes implementation in WP using available layout data. Also, seeing some progress being made on the browser side implementing the new auto sizes HTMLHTML HyperText Markup Language. The semantic scripting language primarily used for outputting content in web browsers. spec, which would be a huge improvement for WP, since we lazy-load many images by default.
  • @swissspidy As for images, I have been looking a bit more into client-side image compression (in GutenbergGutenberg The Gutenberg project is the new Editor Interface for WordPress. The editor improves the process and experience of creating new content, making writing rich content much simpler. It uses ‘blocks’ to add richness rather than shortcodes, custom HTML etc. lately to see where this could fit in 2024 plans.

  • @swissspidy No update either from my side, though I just published a small blog post to help spread the word a little bit about PluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the Plugin Directory or can be cost-based plugin from a third-party Check
