Setup

Install Memcached:

> apt-get install memcached php5-memcache

Edit roundcube config file roudcube/config/main.inc.php

$rcmail_config['imap_cache'] = 'memcache';
$rcmail_config['session_storage'] = 'memcache';
$rcmail_config['memcache_hosts'] = array('localhost:11211');

Eventually edit the cache size in /etc/memcached.conf

# memory
-m 255

If you want to check the memcached memory usage do:

> telnet localhost 11211  
> stats  
> quit

Restart memcached and apache

> service memcached restart  
> service apache2 restart

If you want to track Memcached, you can use various tools like:
