Very poor network performance gigabit-lan
Dec 31, 2011, 9:35 AM
i have a gigabit-lan but my the network performance is (dependent from the send-direction) very poor.
1 pc with win xp, 1 with ubuntu
i measured with iperf, here are the results:
ubuntu as server (iperf -s)
win xp to ubuntu (iperf -c): bandwith about 50 Mbits / sec
ubuntu as client (iperf -c)
ubuntu to win xp (iperf -s): bandwith about 644 Mbits / sec
question: why is bandwith from win xp to ubuntu so poor?
thanks for your resonses.

Without fully reviewing the source code I can only guess, but probably iperf has a bug when complied for Windows.

Transfer a large file both ways to determine if there's a performance issue.
