Hi. Your question is pretty general, and most of what people would write is just a repeat of what it well documented a few other places. Allow me to kindly direct you to: http://httpd.apache.org/docs/misc/perf.html and http://www.daemonnews.org/200108/benchmark.html They should help you quite a bit. If you go through all that and still have out of control loads, you might need to throw some hardware at the problem. Also, it helps others on the list (and people digging through this later in archive form) if you have a subject line relating to the issue.
