New issue 17 by sekharnv73: Client send buffer is not considered and  
reported in the results when it is low.
http://code.google.com/p/ndt/issues/detail?id=17

What steps will reproduce the problem?

1. Connect server and client in a 1GBit Switch
2. Start both servers (fakewww and web100)
3. Set the following tcp paramters in both server and client.
        echo 1 > /proc/sys/net/ipv4/tcp_moderate_rcvbuf
        echo 4194304 > /proc/sys/net/core/wmem_max
        echo 4194304 > /proc/sys/net/core/rmem_max
        echo "4096 65536 65536" > /proc/sys/net/ipv4/tcp_rmem
        echo "4096 8912 8912" > /proc/sys/net/ipv4/tcp_wmem
        echo "1" > /proc/sys/net/ipv4/tcp_timestamps
        echo "1" > /proc/sys/net/ipv4/tcp_window_scaling
        echo "1" > /proc/sys/net/ipv4/tcp_sack
        echo "0" > /proc/sys/net/ipv4/tcp_ecn
4. Click the start button to start the test and wait till client complete
the test.
5. Check the statistics window.

What is the expected output? What do you see instead?
Since the send buffer is low in both server and client which are limiting
the throughput both should be reported but only server send buffer is
reported in the
statistics window, client send buffer problem not reported.
