[netperf-talk] How to use '-b' option?

[Jay Kim]

Hi, I have a problem whn trying to use '-b' option.

I've found the following information from the manual page;

NOTE: If you would like to "pace" the send rate of the UDP_STREAM test, add a -DINTERVALS to the makefile, do a "make clean" and re-compile. You can then use the -b and -w global options to set the burst size (sends) and wait time (milliseconds) respectively. 

So, I recompiled the netperf binaries (actually, define WANT_INTERVAL to 1 in config.h.in file), but '-b' option didn't work.
What I've got is like the following. Any comments or help will be appreciated.

$ netperf -H 10.89.1.122 -tUDP_STREAM -- -b 10 
Initial request burst functionality not compiled-in!
UDP UNIDIRECTIONAL SEND TEST from ::ffff:0.0.0.0 (0.0.0.0) port 0 AF_INET to ::ffff:10.89.1.122 (10.89.1.122) port 0 AF_INET : histogram : interval
Socket  Message  Elapsed      Messages

  8192    8192   10.00      114521      0     750.55
  8192           10.00      113762            745.58

It seems that the burst size function was not compiled in, but using '-w' option was working.
