<p>I needed a persistent object cache while doing work on a budget hosting provider.  A lot of the other file-based caching plugins were either bundled with other things I didn’t need (W3 Total Cache), or were old and broken.</p>
<p>On the sites I’ve tested this with, that have slow database servers, I have noticed an increase in page generation times of about 2x.  On the other hand, for sites that have fast database servers it can actually <em>increase</em> page generation time.  Whenever possible, I’d recommend using Memcached, Redis, or your other quality cache of choice.</p>
<p>I’ve been heavily influenced by <a href="https://wordpress.org/plugins/redis-cache/" rel="ugc">redis-cache</a>, <a href="https://wordpress.org/plugins/wp-redis/" rel="ugc">wp-redis</a>, <a href="https://wordpress.org/plugins/w3-total-cache/" rel="ugc">W3 Total Cache</a>, and <a href="https://github.com/Automattic/wp-memcached" rel="nofollow ugc">wp-memcached</a> to name a few.</p>

<h3>IMPORTANT NOTE ABOUT THIS PLUGIN:</h3>
<p>After careful consideration, we’ve decided to merge the free versions of WP Meta SEO, WP Speed of Light, and WP Latest Posts into their respective premium versions. This consolidation will allow us to focus our resources on developing more robust, feature-rich extensions. We do offer some easy migration and prices for free users though.</p>

<p>WordPress does not have a system for speed optimization by default. That’s why you need a powerful plugin that speed up WordPress with technical and advanced features, yet accessible to everyone.<br />
WP Speed of Light starts with an advanced static cache, plus, you got a file minification and group tools, a database cleanup system, a .htaccess optimization, an auto-cache cleaner and a full CDN integration.</p>
<p>When it comes to performance loading time, it requires some test to identify which plugin, theme, page may require more attention.<br />
WP Speed of Light also includes a speed loading test and compare, and a database queries test. To go one step beyond with your WordPress speed, a PRO ADDON upgrade (optional) with custom support is available.</p>
