[Iperf-users] Different iperf UDB behaviour on Fedora 14 and 18

[Freeman (X. W. <fre...@br...>]

Hi

We were test iperf UDP and found with old releases like Fedora 14, iperf TX side does not know the limitation of the link and keeps send at a data rage specified by the command line, so at the TX side we observe lots of packet drops. However, with Fedora 18 and above, it seems iperf UDP traffic is self-regulated and automatically find out the best data rate, and the RX side hardly shows any packet drop.

Anybody know the reason? It looks we actually ran the same version of iperf 2.0.5 on both systems.

Thanks
