There's so many of them: Chez, Chicken, Gambit, Gerbil (Gambit-based), Racket, Guile.
Compile time matters, runtime perf matters more, std lib matters quite a bit I'd say.
Anyone tried them all — or multiple of the above? Any others I've been missing?
Oh, and "not abandoned and bitrotted" also matters.
Apparently Racket has used the Chez incremental compiler since v8.0. Racket's profiler can be imported with (require profile) and Guile's is (use-modules (statprof)), haven't found something similar for Gambit so far besides `gsc` taking a `-track-scheme` parameter.

Nice, it's interesting how s7 jumps up for tests like cat and tail
Chez Scheme is very fast. Racket too now.
