Lots of fun! ... yea yea :-) It reminds me an 2 years old feature in our product (was QARobot originally, now it's a part of RouterTester) where we had an Session Storm module generates HTTP traffic with kernel support too. I did remember how it was killing any httpd server in secs even from one slave with possible up to 20 with thousands ssm's running on each cpu. Unfortunately it's obsolete now (qa and development, but code and qbol language support still be inside new product for free :). I may try to find some performance data tomorrow if it's interesting for you off cause... Igor.
