I'm searching a system that could be used for performance test training, since I will run a workshop on performance test and would like to use the system, if available, for performance counter analysis & troubleshooting, hotspot analysis, thread dump analysis and how to fix it.
No OS restriction but one must be free. I just want a system that has some obvious bottleneck which could be easily fixed so this would be better.
I tried to Google but no such system was found. Wonder if there's bright idea here or enlighten me. Thanks very much.
