The apache program comes with a program called 'ab' that allows you
bench requests against a server, the only problem is that it completely
blasts the @#$@#$ out of the server because it does requests as fast
as they are completed, you can limit the number of concurrant requests
though.  You also can only specify one url, however you could script
several runs of the program hitting different images/cgis.

Anyone know any others?
