replied this but it's pending moderation so may not appear yet: * the first benchmark you’re referring to isn’t using the most optimized compiler flags for nim, see https://github.com/lh3/biofast/issues/21#issuecomment-707979684 where you can get easily a 1.5x speedup by using `-d:danger –gc:arc` * worth mentioning is you can embed a python session using nim (or vice versa) via https://github.com/yglukhov/nimpy so your can integrate either way * see also https://github.com/timotheecour/D_vs_nim for a D vs nim comparison * not mentioned in this article is that nim compile times are far better than typical equivalent idiomatic code in C or in particular C++ Run
can someone please also check what would the speedup with `--gc:arc` be in <https://github.com/kostya/benchmarks> ? right now it doesn't use this flag, see: <https://github.com/kostya/benchmarks/blob/7c13e9221c4e58f95151864b5db87363a38734b2/common/commands.mk#L4> ? such benchmarks have their importance to attract people, so might as well make use of them in timely manner
