How do you get that C# is way behind Go on this one? If anything, those benchmarks show these groups of languages performing at roughly the same level:
I agree that my wording is too strong due to my memory of the latency results. As you increase the load, Go is closer to Rust/C than C# (see last benchmarks) and at a given load, C# isn’t in picture. It’s fair to say that Go/C# is similar while Java is far behind depending on the benchmarks that are important to you.
