<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>
