[netperf-talk] How to use -D option

[Jay Kim]

Hi, I'm wondering how I can use -D option.
I've re-compiled netperf with --enable-demo option to use -D option, but it seems not printing output messages per second as I expected.
Please check the following output.

$ netperf -H demeter -D -t UDP_STREAM -l 20 
UDP UNIDIRECTIONAL SEND TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to demeter (10.89.1.122) port 0 AF_INET : interval : demo
Socket  Message  Elapsed      Messages                
Size    Size     Time         Okay Errors   Throughput
bytes   bytes    secs            #      #   10^6bits/sec

  8192    8192   19.99       28431      0      93.20
  8192           19.99       28431             93.20


During 20 seconds, the output line is only one line as above. What can be wrong here?

If anyone can provide example output of using -D option, that would be greatly appreciated.
Thanks.
