强烈推荐robocat · 原文2020年5月

说明

这是2019年由Strange Loop Conference发布的一部演讲，主题归在Software performance & optimization。它讲的是performance measurement这一支里的具体问题，而不是把整个领域扫一遍。适合已经能看懂基本术语、想继续往下走的人。内容上可以概括成：Emery Berger explains why performance is hard to measure and deliver on modern hardware, showing how code layout and alignment can swamp optimization effects. He presents Stabilizer for statistically sound evaluation and Coz, a causal profiler.这些读者给出的理由，核心是：It is the standard recommendation for anyone puzzled by unexplained benchmark changes from tiny code edits, and for learning about causal profiling.讲法不绑某一条新闻，过几年仍然可以当材料看。从2019年到2025年，有12位不同的读者在10个不同月份把它推荐出来，其中明确叫别人去看的有5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performance measurement变成能跟着复述的例子。
