[jira] Created: (HARMONY-3227) [jvmti] significant performance
degradation when turning-on jvmti on linux em64t
[jvmti] significant performance degradation when turning-on jvmti on linux em64t
--------------------------------------------------------------------------------
Key: HARMONY-3227
URL: https://issues.apache.org/jira/browse/HARMONY-3227
Project: Harmony
Issue Type: Bug
Components: DRLVM
Environment: linux-em64t
Reporter: Rustem Rafikov
Attachments: jvmti-monitor-capa-check.em64t.diff
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.
