CPU and memory usage varies based 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 for what is normal for a particular installation. A server process should not consume an inordinate amount of CPU for a long period of 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 the Group Chat Server is consuming 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, check the Performancetab in Task Manager.
Repeat this procedure on each computer that hosts a server.
