XVideoSharing: Memcached mod

When your site get popular you can face some overload problems even on a high-end server.
Memcached mod will help you to drop database load a lot. It caches popular DB queries for 30 seconds, so often-used requests won't hit the database anymore.

We're caching these kinds of queries:

• Sessions check
• Folders list
• My Files statistics
• Categories list
• Searches
• Servers list
• Single File records
• More Files lists
• File tags list
• File votes

You can check current memcached stats and flush all cached from admin area.

Installation instructions:
1) Install memcached daemon & required Perl modules:
yum install memcached perl-Cache-Memcached perl-Digest-SHA1
2) Start daemon and add it to autostart:
/etc/init.d/memcached start
echo "/etc/init.d/memcached start" >> /etc/rc.local

You can change memcached max connections / max size limits in it's config:
/etc/sysconfig/memcached
