> @dongjoon-hyun I created jira-issue 1232 for this problem. Also, even the metrics is disabled by setting nullptr, there is still some cost of initing the AutoStopWatch object and destructing it. The following perf flamegraph shows the cost. Although the extra time may be trivial, it may be better to be disabled at compile time. I am confused about why does the chrono time function call still appear in the flamegraph after disabling the metrics. -- This is an automated message from the Apache Git Service.
