I ran the test again - and the results are the same - 
This is Quad Core with 4GB of memory (OC to 3Ghz)

The kernel uses app. 80% system everytime the it actually starts
doing something that is not disk bound - really weird - I have included
the script and the results

PS. Script is not pretty ;-)
