CPU and memory usage varies depending on the specifications of the host computer and the computer load. Check the usage at approximately the same time every day to get a sense of what is typical for a particular installation. A server process should not consume a large amount of CPU for a long time. For example, a process using 95% of the CPU for more than a few seconds indicates a problem. Similarly, the memory usage should be fairly consistent from day to day. If Microsoft Lync Server 2010, Group Chat  is using all available memory and your host computer complies with the minimum system requirements, there may be a problem with the system.

To monitor CPU and memory usage in Windows Server operating systems, check the Performance tab in Task Manager.

Follow these recommendations for each computer that hosts a server.
