optimize apache 2 in centos 5

sokha · 03-28-2010, 10:26 PM

I saw many people were talking about how to optimize apache and mysql here and also in other forums and blogs. I am currently hosting some sites and some IRCD processes (a tiny network)in a dedicated server with spec:

Quote:

Intel Dual Core 1.6GHz E1200
1GB RAM
160 HDD
10Mbits port

We got about 30,000 to 40,000 page views per day. I would like to ask people here about the opinion of apache and mysql optimization based on this server spec and current number of page view.

Looks like a very quiet system to me. Are you actually having a performance issue; if so, what are the symptoms?

The time I run that top command, there was no issue. But before I noticed that it almost run out of memory.

If we put files to let people download, does it make the server overload?
