[Users] Does OpenSER support more than one CPU, performance testing procedure

[rod]

Hello all,

I'm guessing if OpenSER supports more than one CPU.
I ask for this to know if I can achieve to double the call per second 
(cps) rate or registration rate using two processors instead of one.

I suppose that many of us have read the excellent "getting started 5" 
guide and use the scripts provided in this guide to start their first 
SER/OpenSER proxy. I would like to know if other users using these 
scripts would like to share their experience on the amount of users 
their OpenSER platform is able to handle, and on which hardware.
It could be interesting if some users can post their OpenSER performance 
(cps, registration rate, number of user) with a particular "getting 
started" script, for example : "Authenticating ser.cfg", "call 
forwarding ser.cfg".
Moreover, it could be great if we could think of a standard procedure to 
stress test the proxy. I have heard of Sipp, so do you think this 
program could be the base of this procedure?

I understand that OpenSER performance greatly depends of the ser.cfg, 
nat configuration, avpops, the database backend, but I think that it 
could be great to delimit some standards configurations and show what we 
can expect on different hardware specifications.

I'm wondering about this, cause I'd like to know if one or two OpenSER 
will easily support 30 000 to 40 000 users, call forwarding, redirection 
to voicemail; or will I have to buy a commercial product to do this.

I have a small configuration (pstn gateway ser.cfg) running with 50 
users, registering every 60s and a peak of 20cps (limited by my pstn 
connectivity), running like a charm on a small Intel P3 700 Mhz with 
256MB (it's a small test box running on my desk).
If somebody could help to define a test, it will be a pleasure to share 
my experience on an IBM HS20 blade with a bi Xeon 3,06 Ghz and 4GB of RAM.

Thanks to all for the daily support,

rod.
