IIRC go wasn't that fast but can feel like it in vscode. IIRC vscode compiles go using the lsp which is faster than launching a process because for some reason, vscode stalls for a second or more before launching a process.

I can't remember how fast D was but iirc it was fairly fast. Actual fastest is my compiler which I don't work on anymore and isn't ready for production. It's the only compiler I know of that hit millions of lines <1s in a non trivial language https://bolinlang.com/
