Hi Genbox, thanks for the kind words. I've never heard of sharplab.io - the speed of C# compilation is not very high on the priorities of CE right now (though we have some issues filed, and some (stale) PRs to help). We welcome help improving it! If you're talking about the speed of other languages than C#, then most of the time is in the compilers itself, not the fairly limited pre- and post-processing we do. We have a pretty sophisticated setup (at least, I think it is...) for handling the 1,500 compiler/language combinations, hundreds of libraries etc (around 2TB of data), but there's always tradeoffs between fast start-up time, manageability and simplicity of adding new compilers, and the run-time performance of running the compilers etc.
