On posts and pages with comments the most timeconsuming part in page creation is translating the smilies to images!
This has now been fixed in WordPress 2.8-bleeding-edge, but if you are not using that (and in production you probably shouldn’t, yet!), this plugin gives you the speedup anyway.
It replace smilies_init with a new one that constructs a more efficient regular expression, resulting in 10 ggr faster handling of smilies replacement.
Note: it uses the ‘e’ modifier to preg_replace to avoid patching any core files. Not all hosts allow this.
<h3>Performance</h3>
A page with 25 comments on an otherwise empty WordPress 2.7 got created on average 28% faster!
Profile of filters on 2.6.5 without plugin on a page with 403 comments:
<pre><code> Total: 7.052s, Filters/Actions: 5.856s (83%), Db: 0.033s (0.5%)
 1. convert_smilies (calls: 403, total time: 3.911s (55.5%))
 ...
</code></pre>
Profile with plugin:
<pre><code> Total: 3.439s, Filters/Actions: 2.174s (63.2%), Db: 0.036s (1%)
 ...
 4. convert_smilies (calls: 403, total time: 0.357s (10.4%))
 ...
</code></pre>
More than 50% faster!

This plugin supports a few features that may improve the performance of page loading and rendering in the browser:
<ul>
<li>Concatenate CSS</li>
<li>Concatenate JavaScript</li>
<li>Execution timing of non-critical scripts
<ul>
<li>Note: Changing script execution timing can be risky and will not work well for all sites.</li>
</ul>
</li>
</ul>
<h3>Testing</h3>
To test features without enabling them for the entire site, you may append query params to a WordPress post or page URL. For example, to test enabling JavaScript concatenation for <code>https://example.com/blog/</code>, you can use the URL <code>https://example.com/blog/?concat-js=1</code>.
Supported query params:
<ul>
<li><code>concat-css</code> controls CSS concatenation. Values: <code>1</code> for ON and <code>0</code> for OFF.</li>
<li><code>concat-js</code> controls JavaScript concatenation. Values: <code>1</code> for ON and <code>0</code> for OFF.</li>
<li><code>load-mode-js</code> controls how non-critical JavaScript are loaded. Values: ‘defer’ for <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script#attr-defer" rel="nofollow ugc">deferred</a>, ‘async’ for <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script#attr-async" rel="nofollow ugc">async loading</a>, any other value indicates the feature should be disabled.</li>
</ul>
<h4>PHPUnit (Docker)</h4>
You can run the PHPUnit tests locally using Docker (no local MySQL required).
First time (or after changing DB credentials):
<pre><code>docker compose down -v
</code></pre>
Run tests:
<pre><code>docker compose up --build --abort-on-container-exit --exit-code-from tests
</code></pre>
Optional overrides (examples):
<ul>
<li><code>WP_VERSION=6.5 docker compose up --build --abort-on-container-exit --exit-code-from tests</code></li>
<li><code>PHP_VERSION=7.4 docker compose up --build --abort-on-container-exit --exit-code-from tests</code></li>
<li><code>PHPUNIT_VERSION=9.6.20 docker compose up --build --abort-on-container-exit --exit-code-from tests</code></li>
</ul>
