----------------------------------------
Summary: add a performance test for the ThreadMonitor feature
Key: GEODE-10359
URL: https://issues.apache.org/jira/browse/GEODE-10359
Project: Geode
Issue Type: Test
Components: core
Reporter: Darrel Schneider
GEODE-8977 found that the thread monitor can impact performance of other
healthy threads on a server.
We should have a JMH benchmark that measures the impact of the thread monitor
on healthy threads. The test would have some number of threads that don't need
to be doing anything (i.e. they can be stuck waiting for something). It should
keep calling ThreadsMonitoringProcess.getThreadInfoMap at a high frequency.
Meanwhile is should have a number of healthy threads that are doing repeated
operations. The goal would be for the thread monitor to have minimal impact on
the throughput of the healthy threads. The test could also see what the impact
is if showLocks and/or batchCalls is true (these are getThreadInfoMap
parameters).
