<li><a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a>: <a href="https://github.com/WordPress/performance/pull/553">Server-Timing API PR</a> has gotten some reviews and is lined up for Monday’s 1.8.0 release
<ul>
<li>Should help us significantly in assessing server timing metrics in the field; we’re currently extremely limited in that regard as the usual tools only give us client-side performance metrics</li>
<li>For example, other than baseline PHP execution time and DB query time metrics, it also includes one more specific metric, to measure the autoloaded options query (which will help us assess the potential impact of <a rel="noreferrer noopener" href="https://github.com/WordPress/performance/issues/526" target="_blank">https://github.com/WordPress/performance/issues/526</a>)</li>
<li>Very large PR (like SQLite) so the more reviews the better, hoping to merge tomorrow for 1.8.0, otherwise will need to punt to 1.9.0</li>
<li>Will be part of the plugin’s infrastructure, so other modules will be able to leverage it to add server timing metrics around their own behavior and validate how much a certain module improves server-side performance in the field</li>

<li><a href="https://profiles.wordpress.org/spacedmonkey/" class="mention"><span class="mentions-prefix">@</span>spacedmonkey</a>: Is there a plan to use the defer API in core themes and plugins? Useful for developers to see it in action and provide a good example
<ul>
<li><a href="https://profiles.wordpress.org/adamsilverstein/" class="mention"><span class="mentions-prefix">@</span>adamsilverstein</a>: Yes, that’s the plan, to use it wherever we can in core, including themes</li>

<li><a href="https://profiles.wordpress.org/johnbillion/" class="mention"><span class="mentions-prefix">@</span>johnbillion</a>: Have any scripts in default themes been identified as being able to support defer? Probably fewer can support async

You’ll get an entirely new DB with some added logic to make the transition as seamless as possible. This is only the install; no content migration.</li>
<li><a href="https://profiles.wordpress.org/spacedmonkey/" class="mention"><span class="mentions-prefix">@</span>spacedmonkey</a>: Do we run unit tests with SQLite enabled?
<ul>
<li><a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a>: We don’t, but that’s a great idea. Maybe we can add an extra scenario to the GH action for PHPUnit that always has the SQLite database active so we can spot any inconsistencies.</li>
