It's also still faster than other parsers in our tests, even on the smallest documents (https://github.com/simdjson/simdjson/issues/312#issuecomment-597223884)--its https://github.com/simdjson/simdjson/issues/312#issuecomment... advantage is just smaller, like 1.1x and 1.2x instead of 2.5x :) It really starts to pull ahead somewhere between 512 bytes and 1K.
