On Gentoo it's called iperf3 but it works.

I thought the instructions were clear but let's try again. When using iperf YOU have to set up BOTH ends of the path, so: 1) On one end - let's say it's your NAS server - open a terminal. In that terminal type mark@plex:~$ iperf -s ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 128 KByte (default) ------------------------------------------------------------ 2) Then, on your desktop machine that wants to talk to the NAS server type this command, replacing my service IP with your NAS server IP mark@science2:~$ iperf -c 192.168.86.119 ------------------------------------------------------------ Client connecting to 192.168.86.119, TCP port 5001 TCP window size: 85.0 KByte (default) ------------------------------------------------------------ [ 1] local 192.168.86.43 port 40320 connected with 192.168.86.119 port 5001 [ ID] Interval Transfer Bandwidth [ 1] 0.0000-10.0808 sec 426 MBytes 354 Mbits/sec mark@science2:~$ In this case, over my wireless network, I'm getting about 354Mb/S. Last time I checked it I hooked a cable between the 2 rooms I got about 900Mb/s.
