I am having a look at tsung and not getting very far yet. Have you had
luck with it and do you really mean as many concurrent users as you want?
I was hoping to use it to simulate my current load while tuning and making
improvements. So far tsung doesn't appear well suited to my needs. I use
persistent connections; each tsung session uses a new connection. I have
multiple applications that have very usage patterns (some web and largely
idle, some non web and almost saturated); tsung has virtual users choosing
a session based on a probability with think times. I know many
programming languages; tsung (and its error messages) is in erlang.

Thanks for this tip. It seems worth a look.
