Well I believe so, but obviously some people in the Hacker News thread do not think so. If a person see a benchmark showing Nim is slower, and also knows that Nim has GC, he/she might think Nim has a heavy runtime and thus cannot be faster.
Someone in the thread said he has 30 years experience in programming, and the only new lang which is really close to C in speed is Rust. I don't know if this is really true, but I think the impression must be from some benchmarks. If Nim claims that it is efficient, then giving an official benchmark is a good idea.
