PickVids"Performance (Really) Matters" with Emery Berger
推荐理由
I highly recommend it. It's mind blowing, but also terrifying
说明
这是2020年由Association for Computing Machinery (ACM)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。适合想看推导、证明或实现细节的人。内容上可以概括成：Emery Berger argues that performance is hard to measure and deliver on modern systems, showing how code layout and link order can swamp optimization effects. He presents tools that evaluate performance more reliably.这些读者给出的理由，核心是：HN points to it whenever benchmarking pitfalls and layout effects come up, as an eye-opening talk on how unreliable naive measurements are.讲法不绑某一条新闻，过几年仍然可以当材料看。从2022年到2026年，有3位不同的读者在4个不同月份把它推荐出来，其中明确叫别人去看的有1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。
