It's cool (and a bit surprising) to see that Nim was so much faster than Go, even on a toy benchmark. I wonder how Nim+httpbeast would compare against Go+fasthttp or Go+fiber on the same hardware, or also Rust and Haskell.
So the nim comparison is a bit of apples and oranges.
Also, the usual caveats of running micro benchmarks against localhost on an auto scaling CPU core...
I'm not sure why its number is quite low though.
