The process I’ve been following is to basically run vanilla WP using Xdebug-profiling, examine the results using <em>webgrind</em> and try to reduce the amount of function calls – as well as their cost. Generally small tweaks, with relatively big benefits. Last week <a rel="noreferrer noopener" href="https://core.trac.wordpress.org/ticket/55005" target="_blank">#55005</a> was also merged in Core, so overall I believe WP 6.1 contains a lot of nice and impactful performance changes – as highlighted by all the updates from other folks above.</li>

<h2>Discussion: <a href="https://make.wordpress.org/core/2022/09/12/lets-make-wordpress-officially-support-sqlite/">SQLite support</a></h2>
<p><a href="https://profiles.wordpress.org/spacedmonkey/" class="mention"><span class="mentions-prefix">@</span>spacedmonkey</a> and <a href="https://profiles.wordpress.org/aristath/" class="mention"><span class="mentions-prefix">@</span>aristath</a></p>
<ul>
<li><a href="https://profiles.wordpress.org/spacedmonkey/" class="mention"><span class="mentions-prefix">@</span>spacedmonkey</a>: Think this is a great idea and could be useful in core for running unit tests and for other projects like <a href="https://github.com/WordPress/wordpress-wasm">wordpress-wasm</a>. Wonder if the performance team should help take on this problem, even if it is to review the solution and ensure that there’s no performance regression.</li>
<li><a href="https://profiles.wordpress.org/aristath/" class="mention"><span class="mentions-prefix">@</span>aristath</a>: Understand that testing could be difficult, so currently converting it to work as a plugin in <a href="https://github.com/aristath/sqlite">this repository</a>. Trying to convert to something that would make sense for core and then publish in the .org repo as a featured plugin. Hoping if this is in the form of the plugin, more people will test and provide feedback. Also noting that the initial proposal focused on small-to-medium sites, but there’s great potential for growth in other areas as well where large sites can take advantage of SQLite.
<ul>
<li><a href="https://profiles.wordpress.org/spacedmonkey/" class="mention"><span class="mentions-prefix">@</span>spacedmonkey</a>: I’ve forked hyperdb and run very large multisites, can provide context here</li>
<li><a href="https://profiles.wordpress.org/aristath/" class="mention"><span class="mentions-prefix">@</span>aristath</a>: We’ll need lots of context once we get rolling – the prospect of pairing SQLite and hyperdb is very exciting</li>
