For the non-pingpong benchmark [1], c++ (300k rps) looks to be around 2x faster than java (150k rps), while the latter is around 2x faster than go (75k rps).

It looks like go's non-compacting/non-generational gc is at play here. Even csharp is faster than go on that benchmark.

The one you posted has no deserialization overhead since its just ping/pong.
