That is useful. How consistent are the results people are getting though? W=

I run with 1M messages the results are generally very flakey=2C 2=2C 4=2C 6=
seconds=20
between different runs. If I use 10M then due to the far longer run time th=
en=20
the differences are will 2 to 6 seconds but the run time is a whole order o=
f=20
magnitude different give a different picture.

Will try and find an hour to run the tests with this CPU selection code.
