This makes me suspicious, since you did not measure standard
deviation or variance. A quick local test with your code looks
ok, though.
One of my students recently made a benchmarking tool.
If you really want to do this properly, you could try that:

I would not require better statistics here, since the speedups
seem to be stable. :)
