If you are going to run it with apache benchmarks try a fresh version of
Apache::Benchmark
http://stason.org/works/modules/Apache-Benchmark-0.01.tar.gz
but actually there is no reason, Benchmark is perfect for that... I have
posted a few examples, so you can roll your own benchmark.
perldoc Benchmark
will be no less helpful
... just plugged this note about Apache::Benchmark so you'd go grab and
try the package before I release it...
