> Hi All,
> I noticed sugnificant performance degradation when turning-on jvtmi on lnx64. The problem is that monitor helpers always use slow path when jvmti is enabled without checking whether the corresponding capability is added.
> The attached pach adds this check jit_lock_rt_support_em64t.cpp.
