Oh, yes, forgot about that :)
I started each version 3-6 times to get some stable results, end wrote down
'Execution ended after' values in ns and then got average value of them. So,
here's the results:
Ubuntu 13.04: 45773009663 ns ~ 45,77 s
Windows 7:    46902343103 ns ~ 46,90 s
Mac OS X:     99100055833 ns ~ 99,10 s

So, yes, it's now obvious, that Mac version is about twice as slower.
