> On clusters with pool subscriptions enabled, a performance degradation was introduced by GEODE-7358 for regular cache operations.
> The {{InternalDistributedMember.getDurableClientAttributes()}} method is indirectly invoked by the methods {{hashCode()}} and {{equals()}} within the {{ClientProxyMembershipID}} class, which is stored in several Java Collection classes across the product (including different types of {{Map}} instances).
> Prior to GEODE-7358 the {{DurableClientAttributes}} class instance was cached within the {{NetMember}} class, but now is created every time the method is invoked, resulting in a performance penalty for regular cache operations on servers with subscription enabled (not only extra garbage, the constructor itself also does some string manipulation).
> Using one of our internal testing scenarios and a java profiler we detected that we create ~24 instances of {{DurableClientAttributes}} using Geode 1.10, but ~ 404.037.243 instances using the latest {{develop}} branch (screenshots attached).
