Hi Dave,

What kind of load scenario are you generating? If possible pass us the
testcase. When running load, disable all the logging. Also try to get the
system statistics on whether you are CPU bound or IO bound. In our lab, we
generated 70cps using a single instance of sipper on single core processor
for a basic call scenario. To go for higher load you need a load
distributer. Sipper comes with a load distributer and statistics viewer in
its commercial version. Load distributer can handle multimillion BHCA, so
for achieving multimillion BHCA you would need a load distributer and
multiple instance of sipper running behind it. Not just message count, the
statistics viewer of sipper reports number of transactions, calls, report on
every type of transaction and consolidation of report on last x duration and
even more.

Thanks
Suriya.

Hi,

I've been experimenting with Sipper over the last couple of days and I'm
very impressed with it. I've used a lot of simulators and traffic tools and
it has a very intuitive feel and is very versatile.

I've been debugging how Sipper schedules traffic with the load option and no
matter how Iconfigure it, I can't seem to get an effective traffic rate over
15 cps. Do you think it should be possible to get 100 - 200+ cps from
Sipper?

Another question I had was about traffic statistics. Is there any mechanism
within Sipper to report on messages sent / received / timed out / unexpected
while running with the load option?

At the moment I'm running Sipper2.0 on Ruby 1.8.6 on windows XP with the
system under test on the local machine along with SIPp as another SIP server
instance to monitor traffic throughput.

Do you have any suggestions on how I could improve the traffic performance?

thanks,

Dave.
