  You can't compare throughput of two totally different programs to decide whether an individual subsystem is faster. The Go compiler is "fast" because it doesn't do much optimization, and because the language is designed to be simple to compile at the cost of worse ergonomics. Why can't it do much optimization? Partly due to their marketing pitch around fast compilers and partly because Go code runs slowly, because it's using a GC designed to minimize pause times at the cost of having lots of them. The algorithmic tradeoffs here are really well known and there are throughput comparisons of similar programs written in similar styles that show Go falling well behind. As it should, given the choices made in its implementation, in particular the "only one GC knob" choice.
