clearing data and cache

[matrix4583]

How do i clear all the cache in my server? because my css server lags since there are a lot of data stored for that server. The only way to stop lag is when I need to restart the css server. Also anyone know how to work with cron job? I would like to add clearing the cache at certian time.
