Subject: Re: [Iperf-users] iperf runs beyond time limit
Hi John
Try to reduce the -w parameter, i know that this parameter is for
the tcp window, but i think iperf send the value of data that you
put in the -w param.
Hope this helps, and best of regards

Has anyone seen this symptom that iperf runs beyond the time limit ?
( In this example ... 2 threads ran 161 and 942 seconds instead of
60 ).
ssh -f -l root 10.10.50.2 iperf -w 256k -f M -t 60 -c 110.110.60.11
ssh -f -l root 10.10.50.2 iperf -w 256k -f M -t 60 -c 110.110.60.12
ssh -f -l root 10.10.50.2 iperf -w 256k -f M -t 60 -c 110.110.60.13
ssh -f -l root 10.10.50.2 iperf -w 256k -f M -t 60 -c 110.110.60.14
