Pavel Pervov commented on HARMONY-3574:


Event reporting is now optimized in the whole JVMTI, so, please, check, that what you've reported
is fixed now and close this issue as fixed, if everything is ok.

>                 URL: https://issues.apache.org/jira/browse/HARMONY-3574
>             Project: Harmony
>          Issue Type: Bug
>          Components: DRLVM
>         Environment: linux and windows 32/64
>            Reporter: Rustem Rafikov
>            Priority: Minor
> Monitor events handling code does not check if the "can_generate_monitor_events"  capability
is requested. 
> It leads to performance degradation when running with jvmti. 
> Typical code is: 
> if (ti_is_enabled()) {
>      // do something
> }
> Need to add VM_Global_State::loader_env->TI->get_global_capability(DebugUtilsTI::TI_GC_ENABLE_MONITOR_EVENTS)
as well probaly in ti_is_enabled() function (if it is used only for monitor events).
