Apache Process question about RAM usage
- by Andrew Fashion
So everytime I load a new page, I notice a new HTTPD process opens, every time I click a page, and each process says it's using anywhere from 2-4.5% of memory. Does that mean every single process is running at that time using 2-4% of RAM? It's a brand new server and I'm the only one on the server at the moment.
Or does it mean all the other processes are dying, and only the new one is active. Because 4% of my 2048MB of RAM is already 82MB for just one process!?!?
Let me know, because I am trying to determine what I need to beef my server up in order to handle high loads of traffic. I'm expect to get 20,000 uniques per day on launch.
I am currently running a Dual Quad Xeon server, with only 2GB of ram, I will upgrade to 8GB or more shortly. Let me know what you suggest!
thank you
