The kernel will do his best to distribute the load evenly between

That's simply a matter of how the programs are written. If you use
multiple threads where possible, you can achieve much higher overall throughput
for a program. - If you have 10 programs, all written the same way, all
using threads, this would make the most use of any SMP system.
But, as it usually is, if you have only single-threaded applications,
you *may* have better luck

If you really want to see your system sweat, just recompile your kernel.
But don't forget to use the parameter "-j". Use "-j" without any additional
numbers. - And I guess, for the first time, you will eat your heart to see
what load your system will be able to take! - For the first time, you
will see, what your system *really* is able to do.
You want some more of this? - Try recompiling ghostscript with "make -j"!
:-)
After that, you'll know that your system is with a load of 110% running
almost idle. It is bored!
If you want 200% CPU-usage, give your system something to do! ;-)
Put some more load onto it!
