When i try that, I get the following error

"iperf3: unrecognized option '--forceflush'"

This is the command I used to verify --forceflush was working:

iperf3 -c hostname --logfile t.out --forceflush -t20

And then a 'tail -f' of t.out confirmed that forceflush is working

Hi Brian,

I am using it like this:

iperf3 -c $SERVER_ADDRESS -p $PORT -t $TIME -i $INTERVAL -f m --no-fq-socket-pacing -N -Z

Am i doing it wrong?

Seems to work fine for me.

Are you using it with the --logfile option? That is required.

Hi,

Is it possible to flush buffer using iperf3? In the following link it says that it is possible to do so using  --forceflush

http://software.es.net/iperf/invoking.html

but it doesn't seem to be working out for me. I have tried it both on iperf 3.0.11 and iperf 3.1.3.

I would therefore be very much grateful if you could tell me how to do that on the current version that i am using 3.1.3.

Thanks in advance.

Arman
