Well, I know this might be off-topic, but I really want to see the comparison of some ((Schemes (like chez)) who claim to have comparable performance with static-compiled language like c) with c. I did some unscientific benchmark and chez is slower of 2x ~ 10x, racket is of course even slower.. but they are unscientific.
I've seen on Reddit and StackOverflow that people want some benchmark between scheme and c. Adding just c implementations for them of course require works, but not so much. If this is considered helpful maybe I'll start translating some of the benchmarks into c.
