Fibers are the right solution to improve Ruby performance

Crystal suffers from other problems. They diverged too much from type annotations and use macros / metaprogramming too much which immensely increases the compile times.

I don't know about Crystal's preformance problems specifically, but I would be surprised if macros would take up much compile time. I would have guessed it was more to do with the fiendishly tricky type inference problem that they set for themselves (ie. global inference + subtyping + union types + inheritance + overloaded methods).

The problem isn’t tricky it just gets very large very quickly.

Metaprogramming is very fast, this is not a problem: very rarely macros can be the bottleneck
