断电维修太正常的操作了，说明房东找的工人操作很正规，而且做完防水也需要风干

其实是 ip 粘包🐶

没看懂啊，是不让打篮球吗

你这个需求 PT+moviepilot 可以实现，网盘不现实

@wisej 后面试过通过 golang 直接调用 winsock api ，延迟发生的点也是一样的

@wisej 我也觉得应该不是 go 的问题，我用 wireshar 抓包看回包很快，但是应用读不上来。
我在当前 Read 之前，调用一次 Read(nil)，就不会有 500ms 的问题了，但是换了另一台 pc ，这个方法并不能解决问题。

@wisej 这次 trace 的 maxprocs 是默认值，https://www.123pan.com/s/WWYTTd-briQA.html 提取码:v2ex

网上搜到了相似的问题，但是没找到解决方法 https://stackoverflow.com/questions/15588961/windows-tcp-socket-recv-delay

@wisej 确实，trace 的时候设置了 GOMAXPROCS=1 ，现象还是一样的

@Puteulanus 没买三方权益包就不能高速下载；买了三方权益包同时是 svip ，可以获得 1024+10GB 高速下载流量，应该是这个意思
