Running the :hisreswallclock version of t/pthread_auto.t
on the original Athlon X2 Dual Core machine with the
'$a **= 1.3' operation now shows a 2X speedup as hoped...

I just built asperl 5.12.3 on win32 and the performance on
4 CPUs with the number of threads set to 4 and the calculation
to $a **= 1.3 got almost 4X speedup. Fantastic!

Has anyone seen performance benefit from the
new auto pthread capability?
When I run the t/pthread_auto.t test on an
AMD Athlon(tm) X2 Dual Core machine I see no
win from pthreads. It would seem that the
performance gain might depend on the complexity
of the calculation being threaded and on the
number of cores.
Data points anyone?
