2nd connection is 'starved'?
iperf 1.7, Linux 2.4.18 (client), 2.4.20 (server).
It seems that when I open two connections, one is not getting any
bandwidth, the other gets everything.
This happens both on IPv6 & IPv6.
Example:
[root --at-- yogi ~]# iperf -c 10.9.201.5 -P 2 -t 30 -i 5 -w 128K
------------------------------------------------------------
Client connecting to 10.9.201.5, TCP port 5001
