Understanding top and load averages

To put it simply, Load Average shows you the Number of processes, waiting to use the CPU(s) of your machine.

This is not a % of the CPU usage.

The CPU can either be 100% used or 100% unused, it cant be half used or 20% used logically.
But the Load Average shows you how many processes will be using the CPU shortly.

CPU Load Average != CPU % Used.

When you say the your Load Averages are: 7.33, 7.43, 7.10

Assuming you had a single CPU:
This means that they are high and if you had a processor 7.33 times faster, it would have done your job instantly.
The load of 7.33 means you made it work 633% more times than what it could have done.

If you had 4 CPU's, then you can say that they are being overworked. Ideally it should have been 4.00
If you had 7 CPU's, then you can say that all are being used at their full potential.
