I ran a dumb Sieve of Eratosthenes benchmark on a few Schemes. I have previously found idiomatic Swift 3,151x slower than C so surely a GC’d LISP can’t do that great, right?
Chicken (compiled) and Chez do great; I would expect Chez to do better on a less numeric example, this kind of array-humping is what Chicken’s perfect for, since it just compiles to C. Chicken’s interpreter is ridiculous, in dev it’s fine for seeing if something works, but you’d never ship that. Racket’s sad, and it gets worse if you try to do anything productive. Biwascheme was impossible to even test properly, but at 10% completion it wasn’t going to do anything useful.
Also, I want to complain about every Scheme having a different way to call the interpreter as a script, and invoke main with command line arguments. NOT A ONE of these are consistent, and only Chicken does what’s reasonable.
