[netperf-talk] netperf4 config file example

[Jose Luu]

Yes, I have been doing it the same way so far, below are my script and results:

The results are not stable, I think there are difficulties synchronizing all the clients which is why I would like to try netperf4. I must mention that I have had success with uperf which does the same thing, but it does not compile on solaris (!).

I will publish the config file generating script if I succeed with netperf4.

Best regards
Jose

  Jose,
   When I want to run a bunch of netperf/RR tests to one Server run to linux systems and use ssh:

   one bat file with ssh: ssh perf@%1 './netperf -p 7000 -H %2 -l 200 -t TCP_RR'    where perf is the user name(you have to do some setup on each and login as the same username). 

  Then I create a larger one(bat file) with the amount I want to run:

  start  netperfRR.bat perfc8 192.168.7.2

  start  netperfRR.bat perfc8 192.168.4.4

  start  netperfRR.bat perfc8 192.168.3.2

  start  netperfRR.bat perfc8 192.168.7.2

  This can be done more efficiently with DNS..among other things but not bad once you have the setup done for ssh.
  Cheers,
  kate
