Depends on what you really want to accomplish.  Shell loops of
radpwtst have often been suggested in the past; I found them painful
to script though.  There is a problem of deltaT (rtt) as well, so you need
parallel radpwtst to actually get to speed and with that you need to
make sure to not send duplicates, yadda yadda yadda.  It's ok if you
want to check a couple of hundred requests.

For benchmarking and pushing servers in the multiple thousands of
reqs/s you probably want something more sophisticated but perl and
Radiator have proven to be able to do that fairly well, even on a
desktop machine;)
