System Resource

CPU Usage

This field displays what percentage of the VMG’s processing ability is currently used.

When this percentage is close to 100%, the VMG is running at full load, and the

throughput is not going to improve anymore. If you want some applications to have

more throughput, you should turn off other applications (for example, using QoS; see

Chapter 10 on page 141

).

Memory Usage

This field displays what percentage of the VMG’s memory is currently used. Usually, this

percentage should not increase much. If memory usage does get close to 100%, the

VMG is probably becoming unstable, and you should restart the device. See
