Haha - I hope you don't die either. Unfortunately, you will see a very significant performance degradation, since you were running on JRockit (it's used with WebLogic on Win32 also) and now you're running with the Sun JDK. If you wanted to verify, I'd recommend installing a temporary WebLogic OTM instance on the Linux server and comparing performance (assuming this isn't PROD).
There isn't a much information on the EventDiagServlet or MediatorDiagServlet (or other OTM utility servlets, for that matter) since they are pretty advanced. Mostly, those of us who have been doing development or performance tuning for years have just built up a knowledge around them. Here is some high-level info, though:

I do plan to write up more detailed information about several of them -- I just need to find the time... You know how that work
