Description
I have installed memcahe on my Ubuntu server and I know it is functioning properly (running on the default port of 11211)
I then installed this module and configured as outlined in the docs:
<?php
$conf = array(
'cache_inc' => './sites/all/modules/memcache/memcache.inc',
);
?>When I benchmark the performance using Apache Benchmark there is a significant reduction in the HTTP Requests per second.
Without memcache I get 20 request per second, with memcache I get 5.
According to the Memcache status:
