Jacob S. Barrett resolved GEODE-7004.
-------------------------------------
Resolution: Fixed
> Optimize ResourcePermission constructor

> Key: GEODE-7004
> URL: https://issues.apache.org/jira/browse/GEODE-7004
> Project: Geode
> Issue Type: Improvement
> Components: security
> Reporter: Kamilla Aslami
> Assignee: Kamilla Aslami
> Priority: Major
> Labels: performance
> Time Spent: 0.5h
> Remaining Estimate: 0h

> PartitionedPutBenchmark with Security Manager enabled shows a performance
> degradation:

> {noformat}
> In stats, we noticed a higher CPU utilization and less puts.
>
> When Security Manager is enabled, every put operation calls
> IntegratedSecurityService.authorize method, which creates new
> ResourcePermission object. Every execution of ResourcePermission constructor
> takes 5 ms. With the optimization, ResourcePermission constructor execution
> takes less than 0.1 ms.
