I did not know about that basho bench. I went to check the documentation and half way through it, i can say that i am moving basho bench high up in my priority list.Thanks for the pointer.

If you want to go from zero to meaningful results quickly I can't recommend basho bench enough. I had to benchmark cowboy recently to verify whether a change actually had positive effects or not. Every ... single .. tool i tried left me wondering if I should just pretend that an average of the throughput and response times is good enough and move on. Don't fall into that trap, it's really easy to write a test driver or two in erlang to test the scenarios you're interested in.

Never tried Tsung, I guess it's alright as well once you get into it.

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?
