Thread:Project:Support desk/How to decrease Mediawiki's server load

For the last weeks I had around ~700 visitors per day, and today my hoster blocked the site due to overload. The hosting supports 600 mb RAM, maximum permissible load of 72 cp (I don't know what that means) and pretty enough space. So, what do I have to do? Do I have to try this? I still didn't it because as memcached requires more RAM I'm not sure if that is about lowering the burden over server.
