Yeah, will be interested in the results, and I'm already guessing the outcome will be positive.

I just finished doing a workshop on Jetpack, and when I was preparing for it I installed it on a live site hosted at GoDaddy. I have no data to back me up, as that was not my intentions, but I can tell you from that experience I sure didn't notice any obvious slowdowns.

In fact, I was really impressed overall after digging into it much deeper than I ever have :)
