Relatively yes, but F# also happens to be faster than other FP languages and has access to a vast ecosystem unlike Haxe. I doubt the public looking at FP languages would appreciate Go :)

F# includes an optimizer that performs e.g. lambda inlining. Then, .NET compiles the assemblies themselves to a final application, be it native executable or otherwise, so I feel like relative compiler slowness is not a dealbreaker. It is also relatively quick at starting for executing F# script files with `dotnet fsi` (I'm happy that F# is included in standard .NET SDK, much different to e.g. Clojure or Scala), it's slower to start than Python or Elixir shell but I can live with that.

This was also a good opportunity to write down a small workflow to use F# interactive to quickly build small native console applications thanks to FSharpPacker:

In the example, the sample program calculates SHA256 hashes for all files matching the pattern at a specific path. On my M1 Pro MBP it does so at up to 4GB/s while consuming 5-10 MiB of RAM.




Well Haxe has access to whatever it compiles to. If i target JS i get the entirety of the JS ecosystem, in good and bad.

F# is indeed fast. Thanks the the work MS has put in. But so is Ocaml, it is close to C when written in perf first mode. Having said that i rarely need the speed of C for what im building, as bottlenecks tend to be IO anyway.

Finally, ocaml 5+ got multicore (domains) and effects, that really is a better abstraction than monads ever will be (imho)


Not all Clojure REPLs have slow startup. Clojure is a hosted language, it sits atop another PL. For instance, REPL of nbb (which runs on Node) is instantaneous, and babashka (for bash scripting) is also very fast.
