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.
