[OpenSIPS-Users] opensips performance testing

[Vlad Paiu]

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 ?

Regards,
