It says it's faster but what's the order of magnitude? 3% ? 30% ? (Not that's important, but since it's mentioned, I'm curious)

If anyone has done a specific head-to-head performance comparison, I was unable to track it down. I believe the hope is that it will be faster because it is (conceptually) simpler and affords more opportunities for caching intermediate results. Hopefully a rigorous performance comparison is part of the plan for stabilization.

There are performance metrics in "This Week in Rust" posts (linked from the Weekly Edition here) as things land. I wouldn't be surprised to see a bit more analysis there when this lands.
