"rustc will never be as fast as the Go compiler" I actually wonder about that.

I guess my skepticism of claims that describe performance in absolutes is that people used to make some pretty strong claims about JavaScript perf too. And then V8 came along and proved that JS could be optimized just fine. It required work, but certainly wasn't impossible.

Go has made syntax decisions to improve compile times, while rust has a lot more static checking to do that go just forces on the user at runtime. I could imagine however that rustc could benefit from some greenthreading

Do you have links for the syntax choices go made based on compile times? I’ve heard this claim but never investigated it, I’m curious what choices

if you take into account the manual work go requires from its users, the rust toolchain is faster than the go toolchain (go + tests + human work)

It's also so hard to compare real timings when size of codebase/complexity (of the involved expressions) can be clearly compared, too, that it often feels like hand-waving. Both feel really fast to me on small projects. I haven't used go's compiler on any massive projects, tho.
