There has to be a problem that I haven't solved, the CPU load is always around 1.6 or so, I need to lower it down some how. I usually have around 150 people on the site at a time, only 20 - 30 of them are members.
Anyways, I have no idea on how to customize nginx, and also for some reason it seems like Apache is still running and that nginx is maybe working side by side with it. I have no idea, but if two webservers are running at the same time, i am sure that isn't a very good idea, please help me with this. I've tried some caching options, i've done the file caching but thats it. I've heard of memcache but I have no idea on how to actually get that installed on my VPS.
So please, If anyone could help me customize / use nginx properly, as well as good caching and optimizing tips. It would be great!
