一、iperf简介
iperf是一个基于Client/Server的网络性能测试工具,可以测试TCP、UDP和SCTP带宽质量,能够提供网络吞吐量信息,以及震动、丢包率,最大段和最大传输单元大小等统计信息,帮助我们测试网络性能,定位网络瓶颈。
iperf的好处是纯粹发包和接收,不会被硬盘、Flash等读写速度影响测试结果。
博主本人测试路由器的无线性能,iperf测试结果在一定程度上反应了路由器的网络性能。
二、演示
PC 与 路由器
路由器做服务端:
iperf3 -s -p 6800
PC做客户端:
iperf3 -c 192.168.10.1 -p 6800 -i 1 -t 30
三、iperf下载地址

The usual prefixes for octal and hex can be used, i.e. 52, 064 and 0x34 all specify the same value. --dscp N or --dscp val set the IP dscp value, either 0-63 or symbolic. Numeric values can be specified in decimal, octal and hex (see --tos above). -L, --flowlabel N set the IPv6 flow label (only supported on Linux) -Z, --zerocopy use a 'zero copy' method of sending data -O, --omit N omit the first n seconds -T, --title str prefix every output line with this string --extra-data str data string to include in client and server JSON --get-server-output get results from server --udp-counters-64bit use 64-bit counters in UDP test packets --repeating-payload use repeating pattern in payload, instead of randomized payload (like in iperf2) [KMG] indicates options that support a K/M/G suffix for kilo-, mega-, or giga- iperf3 homepage at: https://software.es.net/iperf/ Report bugs to: https://github.com/esnet/iperf
