iperf3 的结果分析疑问

1G 网络传 512K 文件，这能准吗……
至少测十几秒吧

[ ID] Interval Transfer Bandwidth
[ 4] 0.0-10.0 sec 12.3 GBytes 10.6 Gbits/sec

测试过百兆 几十 M 都一样 10M 到 1.6G 的跳 1/10 的概率 100M 以下

关键在于网络传输的数据 99% 是 500K 以下的数据 是 API 服务器

iperf 跑几分钟，然后 netstat -s 看下哪里不正常吧

netstat -s 如何分析？ 求科普

你们俩这头像看着真是精分……

@webdev 那你这样单线程测 500K 文件，也是不准的，除非你的 API 同一时间只能接受一个连接

@webdev
Tcp:
3 active connections openings 3 个主动连接
1 passive connection openings 1 个被动连接
0 failed connection attempts 连接失败
2 connection resets received 2 个连接被重置
1 connections established 已建立 1 个连接
111817 segments received 收到的包
72082 segments send out 发出的包
4 segments retransmited 重发的包
0 bad segments received. 接收到的错误包
0 resets sent 已发送的断开连接次数

@lhbc 多谢 玩待会多测试下

帮忙分析下？ 刚跑了 2 分钟 平均速度 220M 貌似不正常

看不出什么问题？
你这是内网？延时多少？上层有没有限制带宽？

@lhbc netstat -s 在服务端跑的 是否应该在客户端跑？

@lhbc 是内网 延时我要测下 带宽限制还真不清楚
