Recently, my host state that my site is using up alot of cpu resources and they want to terminate my site. Please take a look at my site http://widep.com Code (markup): and any ideas on what are the potential causes? I've already have cache activated, but not much effect.
If you're using mysql I'd look there first run some performance monitoring commands, you may be missing some indexes or something like that.
Did they tell you what kind of processes that are taking up these resources? apache or mysql related?
If you are receiving a lot of connections to your Mysql DB for your torrent site, its possible that you might need to upgrade to a VPS solution to host the amount of traffic you get.
