#45 iperf 2.0.5 bidirectional udp not in full duplex

[Sergey Naumov]

I got iperf 2.0.4 as debian squeeze package, 2.0.5 I got from wheezy and installed it on squeeze.
Client and server connected through router.
Server: iperf -s -u
Client: iperf -c 192.168.1.1 -t 60 -i1 -xC -xS -xV -xM -L60001 -u -b1000M

In client's report I have smth like this:
iperf 2.0.4 for client and server:
... 943MBit/s
... 943Mbit/s 0.025ms 20/80000(0,02%)
iperf 2.0.4 for client and 2.0.5 for server:
... 943MBit/s
... 405Mbit/s 0.025ms 20/40000(0,04%)
iperf 2.0.5 for client and server:
... 405MBit/s
... 405Mbit/s 0.025ms 45000/80000(58%)

It seems that iperf 2.0.5 doesn't use full duplex.
