---------------------------------------

DonalEvans opened a new pull request #5862:
URL: https://github.com/apache/geode/pull/5862


   - OperationExecutors.MAX_THREADS new default is 300
   - ClusterOperationExecutors.MAX_PR_THREADS new default is
   Math.max(Runtime.getRuntime().availableProcessors() * 32, 200))
   - Removed unit test case for setting system property, since it cannot be
   cleared afterwards without unloading the class

>             Project: Geode
>          Issue Type: Improvement
>    Affects Versions: 1.14.0
>            Reporter: Donal Evans
>            Assignee: Donal Evans
>            Priority: Major
>
> Similar to GEODE-8780, the default maximum number of pooled message processor and partitioned region message processor threads are low enough that they can cause performance degradation and should be increased.
> The current default value for {{MAX_THREADS}} is 100, and the current default value for {{MAX_PR_THREADS}} is 
> {{Math.max(Runtime.getRuntime().availableProcessors() * 4, 16)}}
> The proposed new values are 300 and 
> {{Math.max(Runtime.getRuntime().availableProcessors() * 32, 200)}}
