Interesting data, poor presentation. The tables need some formatting and colors would be nice, too. Instead of "slower" and "faster" it should be just a factor. So, 2x would mean that it takes twice as long and 0.5x would mean that it's twice as fast. Also, what's the baseline? Where does that 1x come from?
