We haven't done any performance testing or tweaking at this point.

Yes and no. It's sort of comparing C and Smalltalk - from the "raw"
perspective of microbenchmarks it will certainly be much slower. Yet, it
won't matter (or not very often) since what you're doing is to 90%
graphics bound and then the added flexibility and resiliency of the
architecture will kick in.
