> 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.
