[LON-CAPA-admin] server load

[Lucas, Mark]

The server load is the system load average multiplied by 100.

If you use the top command you can see the load average at the top of the screen and you
may also gain some insight into the process or processes that are taking up CPU time.

There may be a background job running. You may also have some other 'runaway' process.
When I am running backups on a machine, the system load goes up even though the user
load is minimal.
