The cause of the slowness is not related to deoptimization done by the test. The following code from vm/mlvm/meth/stress/compiler/deoptimize/Test.java runs very slow in fastdebug MHTransformationGen.createAndCallSequence(retVal, dataSnapshot, _mh, _finalArgs, true); Here the results of running modified test with 40 threads where each thread just runs MHTransformationGen.createAndCallSequence(...) once and exits. product: 3.5 sec fastdebug: 2m38 sec

This is debug build issue. On my 24 cpu machine the test takes 16 minutes using fastdebug build against 10 seconds using product build. I will look more what is going on in case fastdebug build is used.
