I've looked into that a little, but here are the two problems I'm wanting to address: 1. How much of the kernel is getting hit on a run of any given test? Even an approximate percentage is fine as long as I can prove it. 2. I could run many many copies simultaneously I suppose and get some stress, but I'd prefer to stress individual pieces one at a time. Those pieces could then be mixed together in later runs for mixed load stress. Additional mixed load tests will be performed with general applications (web servers, databases, etc) for more of a "real world" environment, but I want to have focused tests as well. I'm betting that there are probably a LOT of quick and dirty test programs that kernel hackers have written to expose a problem or thoroughly test a piece of the kernel that they modified. These type of things would be FYI this project will be going on sourceforge very soon. I want to have a little more to start out with though and finish putting together a good project description, testplans, etc. to post as soon as we put it on there. I hate it when people start projects and you don't see any good information about it for weeks.
