推荐理由

It's worth looking at if you're into this sort of thing.

说明

这是2020年由InfoQ发布的一部演讲，主题归在Software performance & optimization。它讲的是fast json parsing这一支里的具体问题，而不是把整个领域扫一遍。适合想看推导、证明或实现细节的人。内容上可以概括成：Daniel Lemire's QCon talk on how simdjson parses gigabytes of JSON per second. It covers SIMD vectorization, branch prediction and the lessons learned building a fast parser.这些读者给出的理由，核心是：HN points to it as the best explanation of simdjson internals and of why fast parsing is rarely disk-bound.讲法不绑某一条新闻，过几年仍然可以当材料看。从2020年到2026年，有3位不同的读者在3个不同月份把它推荐出来，其中明确叫别人去看的有0次。适合一次性看完。讲者把一个判断讲透，演示是在给这个判断配例子。如果已经会了基本定义，就把注意力放在它怎么把fast json parsing变成能跟着复述的例子。
