As this mainly concerns GC profiling I've cc'ed the GC list.

As my experience with profiling the hotspot on Windows (using Visual Studio), the generated of profiling data is huge (2-6GB) and in many cases, my computer could not handle the analysis of profiling data. In addition, hotspot's code and its build are quite complex, I want to consult some opinions first before actually do it.
