I don't think additional ram would help. You have not used any of your swap space, which indicates that you are not lacking for RAM. You are running a VERY high number of processes. Can you tell me what the box is used for and what the apache Max Clients is set to?

A system's load is the number of processes that are ready to run, including ones currently running. This number is measured at regular, frequent intervals. The load average, therefore, is the average of this load number over a particular interval of time. There actually are three load averages measured over different periods of time: the most recent minute, the last five minutes, and the last 15 minutes.

Ram and cpu look good but load is super high. Maybe I should lower the settings in httpd.conf I guess 2000 max cleints is a bit high for apache
last pid: 1710; load averages: 46.00, 35.31, 26.958 up 0+03:10:07 12:54:31

300 might be way too low. People would get locked out

Its not so much about how many people get locked out, it is about setting it so that the server gets as many connections open as it can handle

Yeah I got some advice from someone that runs high traffic servers. He said as long as it's not swaping and I have enough cpu idle things should be good.
The high load scares me a bit though.

High loads scare everyone  nothing to worry about as long as they system is always responsive, isn't digging heavily into the swap, and theres 30%+ idle cpu on average
