Assertivlogix Simple Cache is a lightweight WordPress plugin that improves front-end performance by caching rendered pages and minified CSS/JS assets to reduce server load and page load times.
<ul>
<li>New: Optional lazy loading for <code><img></code> tags. Enable the checkbox in the plugin settings to automatically append <code>loading="lazy"</code> to cached HTML when your theme or host does not already handle it.</li>
<li>Advanced CSS controls: remove unused selectors and duplicates, combine local stylesheets into an async-delivered bundle, and inline auto-generated or manual critical CSS for faster first paint.</li>
</ul>
<h3>Compatibility</h3>
This plugin relies on <code>ob_start()</code> buffering and is not supported on servers that already provide full-page caching at the base/server level (e.g., managed hosts with Varnish, LiteSpeed cache services, or proprietary edge caches). Combining two page caches can cause double-caching, stale pages, or broken purge flows, so we cannot offer support for those environments.

Minification & concatenation of JS and CSS files can reduce the file size of your assets, and reduce the number of HTTP requests, helping improve page load times.
The plugin takes a manually defined list of script/style handles, and minifies and concatenates them into a single file which is then cached for future use.
Features.
<ul>
<li>Minifies & concatenates scripts and styles loaded using the WordPress dependency enqueueing system.</li>
<li>Handles scripts loaded in the header & footer.</li>
<li>Complete control – only a manually defined list of files is processed.</li>
<li>Multiple, independently processed files.</li>
<li>Minified files are only loaded if at least one component file should be loaded.</li>
<li>Compatable with localized scripts.</li>
<li>Helper tool – displays a list of scripts and styles enqueued on each page on the front end of the site.</li>
</ul>
