Comments on: Performance testing – buried by an avalanche http://watchitlater.com/blog/2008/04/performance-testing-buried-by-an-avalanche/ A reluctant foray into the world of blogging.

It is only an edge case, but when doing destructive testing, you really want to keep on sending requests, no matter what the state of the server is. I know that I'm being really pedantic here, but the blocking calls made by JMeter trouble me, as does scaling up using threads. Nervertheless I'll keep on using Grinder and JMeter till I stop being distracted by shiny things and finish off Thumper.

However it wont back-off. But you can size the thread pool accordingly, so you will never get more parallel requests than threads configured. Since the fixed-rate timer cant sleep negative time, its quite safe... Bernd Apache JMeter has a constant rate time. However it wont back-off.
