Thus, roughly speaking, simdjson can parse, validate a JSON document and create a DOM tree, at a speed of about 2 GB/s. The easier-to-use “JSON for Modern C++” has a speed of about 0.1 GB/s, so about 20x slower. As a reference, we can easily read files from disk or the network at speeds higher than 2 GB/s.

速度差20倍，估计进不了标准库
