I haven't done a controlled comparison, but a tight loop in RB is just 
about as fast as a tight loop in C (using immediate mode OpenGL at 
least). Where things start to go off is when you introduce an event 
loop - in C you have total control, so you can pick and chose what to 
deal with and what to ignore, and how often to yield to background 
tasks. In RB, you're a slave to the runtime.
