If I execute Iperf(version 2.0.5 (08 Jul 2010) pthreads) client with "iperf -c 192.168.2.1 -u -fm -t60 -d -b 10m -w 4m" command, Iperf server with "iperf -s u -w 4m" command, Iperf client with "iperf -c 192.168.1.1 -t 60 -w 2m" command etc, I get the "TCP window size: 50.0 KByte (WARNING: requested 2.00 MByte)", "UDP buffer size: 0.01 MByte (WARNING: requested 4.00 MByte)" or similar warning. In other words the value of the "-w" flag seems to be ignored. One example:
[root@ ~]# iperf -c 192.168.2.1 -u -fm -t60 -d -b 10m -w 4M ------------------------------------------------------------ Server listening on UDP port 5001 Receiving 1470 byte datagrams UDP buffer size: 0.04 MByte (WARNING: requested 4.00 MByte) ------------------------------------------------------------ ------------------------------------------------------------ Client connecting to 192.168.2.1, UDP port 5001 Sending 1470 byte datagrams UDP buffer size: 0.01 MByte (WARNING: requested 4.00 MByte) ------------------------------------------------------------ [ 4] local 192.168.1.1 port 31589 connected with 192.168.2.1 port 5001 [ 3] local 192.168.1.1 port 5001 connected with 192.168.2.1 port 38678 What might cause this? I Googled with 'iperf "WARNING: requested *"', but found anything useful. regards, martin ------------------------------------------------------------------------------ Create and publish websites with WebMatrix Use the most popular FREE web apps or write code yourself; WebMatrix provides all the features you need to develop and publish your website. http://p.sf.net/sfu/ms-webmatrix-sf _______________________________________________ Iperf-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/iperf-users
