网络工程 - Iperf 关于带宽和传输的结果没有意义 - 吾爱随笔录

我无法理解为什么 iperf 的行为方式如此。我只是想将 UDP 流量从 Raspberry Pi 发送到我的计算机。

这是它在客户端的样子：

pi@raspberrypi:~ $ iperf -c 192.168.0.5 -t 10 -i 1 -u -b 10000m
------------------------------------------------------------
Client connecting to 192.168.0.5, UDP port 5001
Sending 1470 byte datagrams, IPG target: 1.18 us (kalman adjust)
UDP buffer size:  160 KByte (default)
------------------------------------------------------------

[  3]  8.0- 9.0 sec  11.3 MBytes  94.8 Mbits/sec
[  3]  9.0-10.0 sec  11.4 MBytes  95.5 Mbits/sec
[  3]  0.0-10.0 sec   114 MBytes  95.4 Mbits/sec

[  3]  0.0-10.0 sec   114 MBytes  95.4 Mbits/sec   0.201 ms    0/81153 (0%)

现在这就是它在服务器端的样子：

Comp-Name:Directory username$ iperf -s -i 1 -u
------------------------------------------------------------

如果我尝试推送 10,000 Mbps 的数据，为什么带宽 (Mbits/sec)和传输 (MBytes)的上限为 ~95 和 ~11.4？

iperf不应该尝试推流量并在封顶后显示损失吗？我在这里遗漏了一些明显的东西吗？
