<ul>
<li>After the initial <a href="https://make.wordpress.org/core/2023/07/24/i18n-performance-analysis/">i18n performance analysis blog post</a> we want to continue testing the <a href="https://github.com/swissspidy/ginger-mo">Ginger MO</a> solution, submit it to the plugin directory ASAP (long queue!), and promote it in the Performance Lab plugin.</li>
<li>It was suggested to find a more descriptive plugin name than “Ginger MO” — <a href="https://github.com/swissspidy/ginger-mo/issues/35">please leave your feedback here</a></li>
<li>Will also ask people &#038; hosts at WCUS to test it in their environments.</li>
</ul>
</li>
<li><a href="https://profiles.wordpress.org/joemcgill/" class="mention"><span class="mentions-prefix">@</span>joemcgill</a> 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 <code>theme_json</code> 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 <a href="https://profiles.wordpress.org/oandregal/" class="mention"><span class="mentions-prefix">@</span>oandregal</a> and <a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a> would probably have the most context here.</li>

<li><a href="https://profiles.wordpress.org/10upsimon/" class="mention"><span class="mentions-prefix">@</span>10upsimon</a> I’ve been working on an ongoing POC for managing standalone performance plug-ins from the performance plug-ins settings screen, I’m <em>almost</em> at a point where I’m happy to share the code engineered this far for further team input.</li>
<li>It’s involved introduction of a class structure and thus some minor additions to engineering infrastructure too (class auto loading etc).</li>
<li>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.</li>
