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. :)
