强烈推荐wmfiv · 原文2020年4月

说明

这是2015年由Strange Loop Conference发布的一部演讲，主题归在Software performance & optimization。它讲的是latency 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：Gil Tene of Azul Systems explains common pitfalls in measuring latency and response time, including why averages mislead and the problem of coordinated omission. He introduces open source tools like HdrHistogram for better measurement and reporting.这些读者给出的理由，核心是：The canonical recommendation whenever percentiles, tail latency, load testing or averages come up, described by some as life changing.讲法不绑某一条新闻，过几年仍然可以当材料看。从2015年到2026年，有9位不同的读者在9个不同月份把它推荐出来，其中明确叫别人去看的有4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latency measurement变成能跟着复述的例子。
