Hi Xiao Feng, Thanks for your help. I found Intel VTune use JVMTI to profile the application if you specify your application as java program. So that it still won't work in my case because I don't use the IR generated from bytecode. But if I specify the java program as a linux excutable application, all I got are hot modules. When I try to see the hot methods in a module, VTune collapse. Thanks a lot.

Personally I do not see any special in using Vtune with Harmony than with another applications.
