Iperf

Hello everyone,
It seams to be a visualization problem with Iperf running on a Ubuntu
machine. I set it as server and start listening on the standatd port 5001.
I start a client and set a ime period of 120 seconds. While the client
displays the measures, there is no output at the server until the 120sec
end. Then it returns the average value and only it.
I have not experienced this same problem with Windows or SUSE.
Do you have any suggestions?
