Nice work. By the way, on the x86 simdjson did you use any of the string compare instructions in SSE 4.2? Or was AVX faster?

- glangdale 7y agoSSE4.2 is bollocks. It was DOA. There are better ways of doing most of it using PSHUFB and what's more, those ways were better when SSE4.2 arrived. It's only gotten slower, relatively speaking, as it is exiled to the edge of the die and has not been promoted to wider regs (AVX2, AVX512).
