The msExchESEParamCacheSizeMin setting still works with E2k7:
But as Mahmoud Amin Ismail said, E2k7 will take all the memory that’s on the server.
The only reason to use this settings is if the server host other services, besides Exchange.
I’ve seen the UI slow down also on E2k7 servers but end-user performance seems fine still.
Our store.exe process has been consuming more and more memory. We have 10 GB installed, and the store is using almost 7. This pushes the total memory used for the server to over 10GB, and is slowing it down. When I reboot, store starts off much smaller, but over several weeks, it inches back up again.
