77% faster is not correct either. "Speed" would probably by ops/s.

4.5x longer = 350% slower.

Even this is confusing as hell.

Just say the native calls take 22% of the time they do on EC2. Or that the EC2 calls take 450% of the time of their native counterparts.

"Faster" and "slower" when going with percentages are ripe with confusion. Please don't use them.

I can't agree. Speed is usually units/time, and everyone knows that 100 mph is 2x as fast as 50 mph, or 100% faster.

This is what decibels are for.
