Lemire himself also worked on a C++ CSV parser with Geoff Langdale that uses SIMD to accelerate the parsing. [1].
Also the fastest library in TFAs benchmark is Sep [2], which makes use of SIMD.

#12Haven't yet seen any of these beat https://github.com/liquidaty/zsv (of which I'm an author) when real-world constraints are applied (e.g. we no longer assume that line ends are always \n, or that there are no dbl-quote chars, embedded commas/newlines/dbl-quotes). And maybe under the artificial conditions as well.
