From Gambit wiki
I am a physicist, mathematician and Gentoo developer. I have used gambit for some semi-serious computer simulations of the Ising model (which is an extremely simplistic model of magnetism). Gambit, Larceny and Bigloo are the highest performing R5RS implementations, although Larceny has the fastest macro expansion, where Gambit's macro performance is extremely poor.
