<li><a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a> Happy to answer any questions on the data I gathered</li>
<li><a href="https://profiles.wordpress.org/spacedmonkey/" class="mention"><span class="mentions-prefix">@</span>spacedmonkey</a> Doing some research, realpath seems to be taking up a lot of resources</li>
<li><a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a> Is the <code>realpath()</code> usage something that was introduced in 6.2?</li>
<li><a href="https://profiles.wordpress.org/spacedmonkey/" class="mention"><span class="mentions-prefix">@</span>spacedmonkey</a> No, but I think it has been made worse.</li>
<li><a href="https://profiles.wordpress.org/joemcgill/" class="mention"><span class="mentions-prefix">@</span>joemcgill</a> After thinking about the original issue some more, I’m wondering if what <a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a> observed is mainly a side-effect of things being moved around in the application lifecycle, which means that there are more callbacks firing on init, but overall the total response time is still an improvement over 6.1.X.</li>
<li><a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a> The overall total response time for classic themes is now actually worse in 6.2 than 6.1</li>
<li><a href="https://profiles.wordpress.org/joemcgill/" class="mention"><span class="mentions-prefix">@</span>joemcgill</a> That’s not what I’m seeing in our automated tests though.</li>
<li><a href="https://profiles.wordpress.org/spacedmonkey/" class="mention"><span class="mentions-prefix">@</span>spacedmonkey</a> It might be related to this – <a rel="noreferrer noopener" href="https://github.com/WordPress/wordpress-develop/commit/6d0a691b84d411813378f1983a0a87bf78a1ccad" target="_blank">https://github.com/WordPress/wordpress-develop/commit/6d0a691b84d411813378f1983a0a87bf78a1ccad</a></li>
<li><a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a> Yeah I also didn’t see that in my previous tests. However what I have consistently seen is <code>init</code> being slower than in 6.1</li>
<li><a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a> FWIW, the automated tests are running core <code>trunk</code> . The tests I have been conducting are using built ZIP releases of the Betas and RCs. Not sure how relevant that is, but it may make a difference</li>
<li><a href="https://profiles.wordpress.org/joemcgill/" class="mention"><span class="mentions-prefix">@</span>joemcgill</a> Even in <a rel="noreferrer noopener" href="https://github.com/WordPress/wordpress-develop/actions/runs/4418025098/jobs/7744568132" target="_blank">the latest run</a>, 6.2 seems like an improvement.</li>
<li><a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a> The ZIP files are in principle closer to the real world experience, that’s why I’ve been using them in addition to the development repository</li>
<li><a href="https://profiles.wordpress.org/spacedmonkey/" class="mention"><span class="mentions-prefix">@</span>spacedmonkey</a> my test runs <a href="https://wordpress.slack.com/archives/C02KGN5K076/p1678812130246649">Slack thread</a></li>
<li><a href="https://profiles.wordpress.org/joemcgill/" class="mention"><span class="mentions-prefix">@</span>joemcgill</a> Zips should be built from the build folder, which is what the automated tests are testing</li>
<li><a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a> request for <a href="https://profiles.wordpress.org/spacedmonkey/" class="mention"><span class="mentions-prefix">@</span>spacedmonkey</a> or <a href="https://profiles.wordpress.org/joemcgill/" class="mention"><span class="mentions-prefix">@</span>joemcgill</a> to run the comparison between 6.1.1 production ZIP and 6.2-RC1 ZIP on your machines? Just to validate, maybe something is off on my environment</li>
<li><a href="https://profiles.wordpress.org/joemcgill/" class="mention"><span class="mentions-prefix">@</span>joemcgill</a> Happy to double check using local profiling at the beta tester plugin later today.</li>
<li><a href="https://profiles.wordpress.org/spacedmonkey/" class="mention"><span class="mentions-prefix">@</span>spacedmonkey</a> I might try using Local envoirment and other tools and see if i can reproduce</li>
<li><a href="https://profiles.wordpress.org/johnbillion/" class="mention"><span class="mentions-prefix">@</span>johnbillion</a> Are all these tests using the theme unit test data?
<ul>
<li><a href="https://profiles.wordpress.org/spacedmonkey/" class="mention"><span class="mentions-prefix">@</span>spacedmonkey</a> I use Fakerpress to make mock data</li>
<li><a href="https://profiles.wordpress.org/joemcgill/" class="mention"><span class="mentions-prefix">@</span>joemcgill</a> The automated tests are. Not sure about how others are testing.</li>
</ul>
</li>
<li><a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a> Good call <a href="https://profiles.wordpress.org/johnbillion/" class="mention"><span class="mentions-prefix">@</span>johnbillion</a> My own local performance testing I’ve done only with the regular WP content (“Hello world”), nothing added. I know that’s not representative of real-world experience, but <a href="https://profiles.wordpress.org/joemcgill/" class="mention"><span class="mentions-prefix">@</span>joemcgill</a> and <a href="https://profiles.wordpress.org/spacedmonkey/" class="mention"><span class="mentions-prefix">@</span>spacedmonkey</a> please try to use that too for specifically the attempt to validate what I’m seeing on my end</li>
<li><a href="https://profiles.wordpress.org/joemcgill/" class="mention"><span class="mentions-prefix">@</span>joemcgill</a> If other folks can do A/B comparisons of the total response time for WP 6.1.1 vs 6.2-RC1 and share data on that issue, it could certainly help.</li>
<li><a href="https://profiles.wordpress.org/spacedmonkey/" class="mention"><span class="mentions-prefix">@</span>spacedmonkey</a> Fakerpress is great for generating posts from multiple authors, adds comments, terms and users.</li>
<li><a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a> So to summarize, just to reproduce, I’m seeing the regression locally in this environment:
<ul>
<li>between 6.1.1 and 6.2-RC1</li>
<li>a site with LocalWP</li>
<li>using TT1 theme</li>
<li>using Performance Lab plugin for Server-Timing, with no modules enabled</li>
<li>no content on the site other than what a clean WP core install gives you</li>
</ul>
</li>
<li>Also see <a rel="noreferrer noopener" href="https://docs.google.com/spreadsheets/d/1LroIJoYz-O9CpfJzaiKYYMWJ7GbE5RZoW1rf1R4FqyA/edit#gid=1935935734" target="_blank">this sheet</a> for more details.</li>
<li><a href="https://profiles.wordpress.org/johnbillion/" class="mention"><span class="mentions-prefix">@</span>johnbillion</a> Are you able to test again with the theme unit test data Felix? That way we have a somewhat unified set of data that’s in use for the tests</li>
<li><a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a> I certainly can. That said though, we also would still need to validate why I see a regression with the default content, so I would appreciate if someone else could run that on their end</li>
<li><a href="https://profiles.wordpress.org/spacedmonkey/" class="mention"><span class="mentions-prefix">@</span>spacedmonkey</a> <a rel="noreferrer noopener" href="https://codex.wordpress.org/Theme_Unit_Test" target="_blank">https://codex.wordpress.org/Theme_Unit_Test</a></li>
<li><a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a> Last but not least, I want to highlight something here (which I tried to also call out on the ticket): <strong>Regardless of whether WP 6.2 is faster than 6.1, </strong><code><strong>init</strong></code><strong> is slower</strong> than before for classic themes. That has surfaced in <em>all</em> performance benchmarks I have done up to date. So while we should validate the overall test results, we should look into what is going on in <code>init</code> and why it has become worse in 6.2</li>
<li><a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a> See <a rel="noreferrer noopener" href="https://docs.google.com/spreadsheets/d/1LroIJoYz-O9CpfJzaiKYYMWJ7GbE5RZoW1rf1R4FqyA/edit#gid=0" target="_blank">https://docs.google.com/spreadsheets/d/1LroIJoYz-O9CpfJzaiKYYMWJ7GbE5RZoW1rf1R4FqyA/edit#gid=0</a> for example. In my new data <a rel="noreferrer noopener" href="https://docs.google.com/spreadsheets/d/1LroIJoYz-O9CpfJzaiKYYMWJ7GbE5RZoW1rf1R4FqyA/edit#gid=1935935734" target="_blank">https://docs.google.com/spreadsheets/d/1LroIJoYz-O9CpfJzaiKYYMWJ7GbE5RZoW1rf1R4FqyA/edit#gid=1935935734</a> this is just more pronounced (which again could be due to a problem on my setup that wasn’t there before). If you want to get those more detailed Server-Timing metrics in your local environment, you can use <a rel="noreferrer noopener" href="https://gist.github.com/felixarntz/63c05392dbf7d51cc7f8f4a424b1ff39" target="_blank">https://gist.github.com/felixarntz/63c05392dbf7d51cc7f8f4a424b1ff39</a> for example</li>
<li><a href="https://profiles.wordpress.org/joemcgill/" class="mention"><span class="mentions-prefix">@</span>joemcgill</a> Back to my initial comment. I am curious if this is a side effect of some things being refactored during this release which has caused more work to be done on the init callback that was previously happening elsewhere. It could be that it’s fine that we’re doing more work on init than we were before if the overall execution time is improved.</li>
<li><a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a> Potentially that’s the case, in which case the “regression” would be fine. But we need to validate that</li>
<li><a href="https://profiles.wordpress.org/joemcgill/" class="mention"><span class="mentions-prefix">@</span>joemcgill</a> I think it would be helpful to review what is hooked to init in 6.2 vs 6.1 and compare differences.</li>

<li><a href="https://profiles.wordpress.org/johnbillion/" class="mention"><span class="mentions-prefix">@</span>johnbillion</a> Briefly from me for a core issue related to performance: I’ve been working to remove use of the now-deprecated <code>SQL_CALC_FOUND_ROWS</code> in core, starting with its use in <code>WP_Query</code>. PR here: <a rel="noreferrer noopener" href="https://github.com/WordPress/wordpress-develop/pull/3863" target="_blank">https://github.com/WordPress/wordpress-develop/pull/3863</a> which continues work from a couple older PRs. There are a few outstanding items to address, I might ask for some help from interested parties on the performance team if I can’t make much progress myself over the next few weeks. Apart from that, the more eyes the merrier on this change!</li>
<li><a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a> Last but not least: Next Monday is the release of the Performance Lab plugin 2.1.0, so we need to get a few PRs ready</li>
<li><a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a> I have been working on a fix for the <code>object-cache.php</code> compatibility issues which I’m about to open a PR for. Would be great to get some reviews today/tomorrow so we can include it in 2.1.0</li>
