Same here, got 11%-24% slower in most regions, and only 3% faster in US-EAST-1. Sao Paulo got 60% faster, though.

Regardless of my results, I've gotta hand it to Amazon on a really kickass speed comparison page. That's a great user experience. It immediately tells me whether I should be using this or not from my particular corporate network without requiring me to waste a day or so trying it out.
