CPU Usage
This field displays what percentage of the NVG2053’s processing ability
is currently used. When this percentage is close to 100%, the NVG2053
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
11 on page 131 ).
Memory
Usage
This field displays what percentage of the NVG2053’s memory is
currently used. Usually, this percentage should not increase much. If
memory usage does get close to 100%, the NVG2053 is probably
becoming unstable, and you should restart the device. See
Section
26.3 on page 223 , or turn off the device (unplug the power) for a few
seconds.
