就是要你懂 TCP | 最经典的TCP性能问题 | 阿里中间件团队博客
问题描述某个PHP服务通过Nginx将后面的tair封装了一下,让其他应用可以通过http协议访问Nginx来get、set 操作tair 上线后测试一切正常,每次操作几毫秒,但是有一次有个应用的value是300K,这个时候set一次需要300毫秒以上。 在没有任何并发压力单线程单次操作也需要这么久,这个延迟是没有道理和无法接受的。

A little bump in the wire that makes your Internet faster | apenwarr
"This approach just feels more magical, because you'll have a physical box that produces negative latency."

Fat flows fill big buffers and then thin flows get stuck behind them, so install a speed bump that keeps track of the different flows (Flow Queueing), puts the thin ones at the head of the line, and throttles the fat ones so the problem doesn't just move to upstream routers/buffers (Controlled Delay).
