Somehow I can't find a source for this but it's well known that Go prefers compilation speed over runtime performance. Doesn't help that they implement the entire compiler stack themselves so it definitely misses optimisations that other compilers can already do.

Also, I've never heard of anyone using assembly for performance optimisations. It would never happen where Go in commonly used (server programming), maybe if you're doing graphics or something nonstandard?

I've done it for a c++ parser. I grabbed the compiled c++ and disassembled it into assembly, then reworked it. Got a massive increase in speed when I tweeked the registry use.

It's in the standard library. It's also how you write parsers and formatters with acceptable performance if you don't have SIMD intrinsics.
