The two graphs shown here inform you about your system load. They are good indicators of the suitability of
your system with its actual use.
CPU load: representation of the CPU usage for the last 24 hours. The
unit used roughly indicates the number of processes trying to
access the CPU at one point. A normal load should remain below 2. Your system is a rather busy one if the load
is between 2 and 5. Above 6, you should
consider upgrading the hardware.
Memory usage: indicates the usage made of your main RAM memory in
megabytes. The different colors give more precise information about
the way the memory is used.
