Any ideas why the compilation is so slow? Compiling a simple "Hello World!" takes a noticeable amount of time on my reasonably well endowed laptop(i5, 4GB ram).

Is it slow just on linux/mono or that's the case on windows as well?

Other than the compilation time, all else seems well. I was following "Programming F#" and didn't run in any blockers on selective examples I tried. Once compiled, the performance is reasonable.

The compiler and interpreter aren't pre-compiled. Use the --resident flag - it will keep the F# compiler running as a service.

Thanks for the tip, the slowness of the F# compiler under mono was bugging me too.
