it was a rough number based on the fps on the command line (which fluctuates)
so 10x is better i would not be able to tell 10x from 11x reliably also i had
some NIST PRNG tests running in the background.
If people care i can pause all other stuff and redo this and post precisse
numbers, but iam not sure how interresting the exact factor for 1 thread 
vs 32 threads is.

thx

Any man who breaks a law that conscience tells him is unjust and willingly 
accepts the penalty by staying in jail in order to arouse the conscience of 
the community on the injustice of the law is at that moment expressing the 
very highest respect for law. - Martin Luther King Jr
