load average?
When you use

it tells you the current time, the uptime, the number of users logged on, and the load average for 1min, 5min, and 15min. What my question is, what do the numbers for load average mean? ie: mine are currently 5.78, 3.17, and 2.27. The first time I used this command, I though these numbers were the percentage that the processor was running at, but how can it run at 578%?

from man 3 getloadavg
    The getloadavg() function returns the number of processes in the system
    run queue
averaged over various periods of time.  Up to nelem samples are
    retrieved and assigned to successive elements of loadavg[].  The system
    imposes a maximum of 3 samples, representing averages over the last 1, 5,
    and 15 minutes, respectively.

It's a way to determine how well the box keeps up
with its work, how many processes need to be waiting
until it's their turn... it's not exactly a measurement of CPU
usage, it also involves IO-waits ...
