I think it's referring to simd instructions [0].
I'm still kind of a newb myself but from what I understand these are special CPU instructions that allow you execute the same instruction in parallel against multiple data points. This allows you to eke out a lot more performance. It's how simdjson[1] is able to outperform all other C++ json parsers.
