Indeed the benchmark was dismissed on Reddit coupe of days ago: https://www.reddit.com/r/programming/comments/h0knmi/go_vs_crystal_performance/ https://www.redd

  The repost[0] in r/golang shows similar critiques. This perf comparison is naive on many levels. - binary size (static vs. dynamic linking) - recursion is not idiomatic in go, it is assumed that you write imperative for loops. - mathematical functions like the Fibonacci sequence are a rather atypical computation use-case for a Go program (I don't know about Crystal). Tree/graph traversal/mutations would be a more fitting test. Or generally something that is composed of dynamically growing and shrinking slices and maps. - http test apparently cannot be reproduced, some get better results for Go, some for Crystal. - http tests w/o involving some parsing/marshaling/serialization or something along those lines aren't that useful. You usually want to either read or send some JSON string or similar.

    Recursion is really not the idiomatic way to solve most things in Crystal either, not that it make the test relevant.

  That said, "was dismissed on Reddit", is one of the less convincing arguments

    Well, it expands into "was dismissed elsewhere, so go there to see if the arguments there are convincing."
