Load testing a server

(this is more of a software recommendation than anything else)

I'm putting together a new server for colo. I've got it pretty much finished, so I wanted to put a load on it and see how it holds up.

I downloaded OpenSTA from www.opensta.org, wrote a test script and configured it to load my server with 400-600 concurrent users.

Here the result of a top command during the test:
Code: 
# top
 last pid:  3007;  load averages: 36.47, 22.99, 10.99
 up 0+20:41:38  16:12:58
 413 processes: 10 running, 403 sleeping
 CPU states: 22.2% user,  0.0% nice, 26.8% system,  4.2% interrupt, 46.7% idle
 Mem: 126M Active, 105M Inact, 94M Wired, 28K Cache, 86M Buf, 425M Free
 Swap: 500M Total, 500M Free

That's FreeBSD 4.5, Apache 1.3.22, php 4.1.1 PentiumIII, 800MHz, 768MB. At one point I had a bit over 500 processes running, pushing out over 6GB of data an hour.

OpenSTA was simple to set up and run. Highly recommended for server testing.
