No, it was faster in "Non-aligned", "Aligned overlap" and "Non-aligned 
overlap" tests. In the "Aligned" case the performance was identical no 
matter if movsb or movsl was used.

I'm also attaching simple sse2 implementation for comparison. It's 
faster than the previous one on my machine. I'm also attaching results 
from running the test on Windows (in VM).

Thanks,
