Owh. Well that sure sped it up :-) So Gambit handles flonums differently from fixnum, huh? I increased the heap and got the the GC to run only 149ms out of the total 14 seconds. Fast enough for me I think, but still a far cry from fixnum performance. Just out of curiosity, is there a way to turn on native floating-point arithmetic? Assuming I'm willing to forego rationals, complex numbers, etc.
Btw Gambit is great. The C-interface is wonderful! And if syntax-case and c-lambda worked together it would be perfect! I'm lovin it ;-)
