They key takeaway really is that for high performance, the way you think about memory layout, data structures, memory management, etc. all start to really matter. It is possible to write programs with memory pools to reuse data structures as much as possible without having to defer the work to the GC, which can then introduce performance spikes.

That said, C# and JVM are both mature and have decades of GC improvements, which could explain why golang is falling behind. Time will tell.
