I have a following very simple setup:
PC1[eth0] <-> [fxp0]PC2
Both PC1 and PC2 have Iperf version 2.0.5 installed. eth0 in PC1 has
IPv4 address 10.10.10.1 and fxp0 in PC2 has IPv4 address 10.10.10.2.
PC1 and PC2 NIC's are connected with straight-through cable.
If I execute Iperf server in PC2 like this:
# iperf -s -u -fm
..and Iperf client in PC1 like this(note the "-2m"):
# iperf -c 10.10.10.2 -u -b -2m -d -t30 -fm
..then PC1 tries to send with 95.7Mbps, PC2 receives at 88.8Mbps and
PC1 receives traffic from PC2 at 76.8Mbps. In other words link is
I'm not familiar with the source code of the Iperf, but as I
understand, in Settings.cpp file there is a "case 'b':" section where
argument for "-b" is read in.
What might cause such behavior? Is this a bug?
