Greetings,
I was asked to do some interbench runs, with various throttle settings,
see below. I'll not attempt to interpret results, only present raw data
for others to examine.
Tested throttling patches version is V24, because while I was compiling
2.6.16-rc6-mm2 in preparation for comparison, I found I'd introduced an
SMP buglet in V23. Something good came from the added testing whether
the results are informative or not :)
