说明

这是2008年由Bryan Cantrill发布的一部演示，主题归在Software performance & optimization。它讲的是disk latency and vibration这一支里的具体问题，而不是把整个领域扫一遍。适合按兴趣直接看、不打算先补课的人。内容上可以概括成：A two-minute 2008 clip from Sun's Fishworks team in which Brendan Gregg uses DTrace to show disk latency spiking while he shouts at a rack of drives. Bryan Cantrill narrates the demonstration.这些读者给出的理由，核心是：It is the go-to viral demo whenever HN discusses vibration, acoustic attacks, or sound affecting hard drives.讲法不绑某一条新闻，过几年仍然可以当材料看。从2011年到2026年，有4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0次。适合先看结果再决定要不要深挖的人。先看它做成了什么。如果已经会了基本定义，就把注意力放在它怎么把disk latency and vibration变成能跟着复述的例子。
