Hello!
I'm wondering what factors are used to determine the "system load"
Where can i look to get more information on this?

system load is the average length of the processor queue.
I would be interested to know where you found that particular language. The man page for uptime says
which is very close to your language. I encountered many cases where this didn't seem to jibe with reality so I took a peek at the source code.
Rather than looking at the run queue, the load is actually computed by scanning the proc table. A process is counted if
- it is runnable (in the run queue)
- if it is running (in a cpu)
- if it sleeping with a priority lower than PZERO
That last one is intended to cover processes that are waiting for disk i/o to complete. And the load is divided by the number of cpu's.
