Hi Richard. Thank you for your interest. Yes, a small speedup as I mentioned
but I'll note that the current kernel code includes the MCORE2 option. I
tested this against some of the newer ones and they are all on par with each
other. For example, here are differences in median values:
CPUDifference in median value
core2 +87.5 ms
core7-avx+79.7 ms
core-avx-i+257.2 ms
I am using ANOVA to establish that the generic group differs from the optimized
group. I have always used ANOVA for this sort of comparison whether using two
or more groups. In fact, thumb through any medical or scientific journal,
you'll see others in pier reviewed article doing the same.
I did not remove any datapoints; I do not understand why you don't think the
sets are normally distributed. Did you see the normal quantile plots?
Additionally, the population variances are fairly equal (Levene and Barlett
tests).
