[erlang-questions] tcp server benchmark

[eigenfunction]

There has been a lot of mails recently about benchmarking stuff. Now i
am faced with the task of benchmarking a tcp server so i am curious.
Is there any simple way out there to benchmark an erlang tcp server
without having to hack some linux script? I was expecting it to be a
simple task but after i started writing the client, i had to stop a
think first about what exactly i want to measure. single client
sending 1000 messages vs 1000 clients sending 1 messages vs multicore
vs single core and it is getting more and more complicated as i think
about it. How do you guys go about it?
Thanks.
