Can anyone tell me if iperf3 is designed to be used with cellular technology and if so what command should I be running. I’ve been running these two commands for ethernet and getting great results.
iperf3 -c xxx.xxx.xxx.xxx -i 2 -t 20 -w 230K -P 3
iperf3 -c xxx.xxx.xxx.xxx -i 2 -t 20 -w 230K -P 3 -R

Subject: [Iperf-users] iperf 2 responsiveness test in 2.1.8-rc, --bounceback option
Hi All,
I've added a low impact, low duty cycle responsiveness test to iperf 2.
Man page is here.
[rjmcmahon@bobcat iperf2-code]$ iperf -v
iperf version 2.1.8-rc (6 August 2022) pthreads
[rjmcmahon@bobcat iperf2-code]$ iperf -s --permit-key=mytest -P 1 --hide-ips
------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 128 KByte (default)
Permit key is 'mytest' (timeout in 20.0 seconds)
------------------------------------------------------------
[rjmcmahon@ryzen3950 iperf2-code]$ iperf -c hostname -i 1 --bounceback --permit-key=mytest --hide-ips
------------------------------------------------------------
Client connecting to (**hidden**), TCP port 5001
Bursting: 100 Byte writes 10 times every 1.00 second(s)
Bounce-back test (size= 100 Byte) (server hold req=0 usecs)
TCP window size: 16.0 KByte (default)
------------------------------------------------------------
