I think that the performance advantage comes from never running Rosetta. An application that can be run in both Rosetta and regular mode will run slower in Rosetta (you can test this yourself by choosing "Open using Rosetta" in a supported Application's Get Info window. I am not sure how Rosetta works, but it may create an overhead on the system in general if any application is using it. Although it doesn't seem to run as it's own process. I think it might be a low level thing that dynamically translates PPC machine code into Intel machine code.

Rosetta process is the "translate daemon"

It is its own process. Look for translated in your ps -aux listing, or in Activity Monitor.
