Hello,
That is indeed strange. What machine were you running on, in terms of
hardware specs ?
Also, are you sure the runtime conditions ( CPU load, network load ) for
all the tests was the same ?
Can you check what is the actual bottleneck when using either 1,4 or 10
children, be it CPU or bandwidth, etc ?

Hi,
I am doing some OPENSIPS performance testing by using two SIPP's. One
SIPP is using a little bit modified UAC scenario and the second one is
using a little bit modified UAS scenario. OPENSIPS is acting as a
stateful UDP proxy without authentification.
I have changed only one parameter in this test bed of mine and that is
children parameter in Global parameters section of the opensips.cfg
file. I was a little surprised to see that the best result
(throughput, presented in the form of cps) I got when used children=1,
than children=10 and after that children=4.
I did 5 tests for each value (of the children parameter) that lasted
180 seconds and after that I did some averaging.
Can anyone give me some explanation for this strange result of mine?
Thanks,
Tarik
