I have not found this slower-than-C to be the case. You may need to use something like `iterator getDelims` in https://github.com/c-blake/cligen/blob/master/cligen/osUt.ni... to manage memory with fewer copies/less alloc "more like C", though or perhaps `std/memfiles` memory mapped IO. More pithy ways to put it are that "there are no speed limits" or "Nim responds to optimization effort about as well as other low level languages like C". You can deploy SIMD intrinsics, for example. In my experience, it's not that hard to "pay only for what you use". As a more concrete thing, I have timed (yes, on one CPU, one test case, etc..many caveats) the tokenizer used in https://github.com/c-blake/bu/blob/main/rp.nim to be faster than that used by the Rust xsv. Of course, you really shouldn't tokenize a lot if it's costly/data is big, but rather
