I have a couple of using complaining of the OCS client running extremely slow. Mixture of Windows XP SP3 and Windows 7 64-bit. When I look at their machine, Communicator.exe will take up over 50% of the CPU and instead of using the normal 39K-40K of
memory, it will be using over 70K of memory and will slowly keep grabbing more memory.
I do not believe that it is an issue with the OCS server, as it does not effect everyone. Nor do I believe it is a network issue and it does not effect everyone on the same network segments.
