<li><a href="https://profiles.wordpress.org/adamsilverstein/" class="mention"><span class="mentions-prefix">@</span>adamsilverstein</a> One new thing this week: I am working on a game/testing tool that shows two images generated by WordPress and asks users which they prefer. The comparisons will cover a range of quality settings and mime types (and image engines) and we will collect data about the comparisons. My goal is both to have something fun and interactive as well as get some actual WordPress based data on image quality to help make a decision about where to set WebP default quality in core.<br />I’d love to have some testers/feedback here once I get it a little further developed (to be shared in future).</li>
<li><a href="https://profiles.wordpress.org/pbearne/" class="mention"><span class="mentions-prefix">@</span>pbearne</a> I will/plan create a combined patch with dom-color with theme flags and media lib changes for core and then create a new proposal blog post on make for this new version<br />Following from <a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a> <a href="https://github.com/WordPress/performance/pull/587" target="_blank" rel="noreferrer noopener">comment on the media lib patch</a></li>
<li><a href="https://profiles.wordpress.org/spacedmonkey/" class="mention"><span class="mentions-prefix">@</span>spacedmonkey</a> asked if we are hoping to get dominant color into 6.2
<ul>
<li><a href="https://profiles.wordpress.org/pbearne/" class="mention"><span class="mentions-prefix">@</span>pbearne</a> would love to get it in but <a href="https://profiles.wordpress.org/spacedmonkey/" class="mention"><span class="mentions-prefix">@</span>spacedmonkey</a> unsure if the 80% rule was met (is it useful for 80% of users)</li>
<li><a href="https://profiles.wordpress.org/pbearne/" class="mention"><span class="mentions-prefix">@</span>pbearne</a> I am hoping as this is a enhancement to the media library and the is for every one we can get it in and with the them flag it can be pulled into a theme if wanted just like you might use the icons from core in a theme</li>

<li>I have a lot of PRs that need code review ^. Some of them have been waiting since November</li>
<li>Anyone on this call can take a look, that would be helpful, specially the core committers, like <a href="https://profiles.wordpress.org/flixos90/" class="mention"><span class="mentions-prefix">@</span>flixos90</a> <a href="https://profiles.wordpress.org/adamsilverstein/" class="mention"><span class="mentions-prefix">@</span>adamsilverstein</a> <a href="https://profiles.wordpress.org/peterwilsoncc/" class="mention"><span class="mentions-prefix">@</span>peterwilsoncc</a> <a href="https://profiles.wordpress.org/sergeybiryukov/" class="mention"><span class="mentions-prefix">@</span>sergeybiryukov</a> or <a href="https://profiles.wordpress.org/johnbillion/" class="mention"><span class="mentions-prefix">@</span>johnbillion</a></li>
<li>I have also been looking into this – <a rel="noreferrer noopener" href="https://github.com/WordPress/gutenberg/issues/45309" target="_blank">https://github.com/WordPress/gutenberg/issues/45309</a>
<ul>
<li>Basically, to get template / template parts for block theme, you have do a database query per part</li>
<li>This can result in 10+ queries per page, even after queries are cached</li>
<li>I am wondering if it makes sense to just load all template parts in single database query and them filter using PHP</li>
<li>The only worry is that you may load templates you do not use or you might have say 40 templates. But that seems unlikely</li>
<li>Templates are not like content, there will not be 20k templates. The benefit of using one query and one cache</li>
</ul>

<li><a href="https://profiles.wordpress.org/olliejones/" class="mention"><span class="mentions-prefix">@</span>olliejones</a> I’m seeing some very promising performance results from using SQLite as the persister for an object cache. Is this worth proposing as a Performance Lab module?
<ul>
<li>Performing very well on a WooCommerce site on low-end Godaddy hosting – been doing some tests on my 100K user test site, it seems good. Also works with multisite</li>
<li><a href="https://profiles.wordpress.org/pbearne/" class="mention"><span class="mentions-prefix">@</span>pbearne</a> suggested yes, <a href="https://profiles.wordpress.org/olliejones/" class="mention"><span class="mentions-prefix">@</span>olliejones</a> will write a proposal</li>
<li><a href="https://profiles.wordpress.org/spacedmonkey/" class="mention"><span class="mentions-prefix">@</span>spacedmonkey</a> +1 for this idea. Adding object caching to sites without the overhead of memcache or redis, could be massive big for smaller sites</li>
<li><a href="https://profiles.wordpress.org/adamsilverstein/" class="mention"><span class="mentions-prefix">@</span>adamsilverstein</a> would be especially great for hosts that don’t support traditional object caching and won’t for some real reasons</li>
<li><a href="https://profiles.wordpress.org/olliejones/" class="mention"><span class="mentions-prefix">@</span>olliejones</a> Last week I asked whether there are any more-or-less standardized large-site benchmarking environments. This is why. Anything?
<ul>
<li><a href="https://profiles.wordpress.org/spacedmonkey/" class="mention"><span class="mentions-prefix">@</span>spacedmonkey</a> You can use WP_CLI to generate 100s of posts, comments or users <a rel="noreferrer noopener" href="https://developer.wordpress.org/cli/commands/post/generate/" target="_blank">https://developer.wordpress.org/cli/commands/post/generate/</a></li>
<li><a href="https://profiles.wordpress.org/olliejones/" class="mention"><span class="mentions-prefix">@</span>olliejones</a> Yes. But it would be cool if we had an accepted PressStone benchmark. Maybe that turns into another module proposal.</li>
