[Serusers] ser scalability

I just wanted to run this by the group.  I did a complete overhaul on one of my ser environments and upgraded the physical server and all software around my sip proxies.  I am also maintaining a complete front end for provisioning and billing that I also moved(PHP/mysql)   I am running this on a Virtual machine (vmware esxi).  If I need more proxies I can clone the VM and build in new service/capacity pretty fast.

I am running 0.9.6 on Redhat ES 5.   I have 4 cores dedicated to this server running Xeon 2.93GHz processers and 4 GIG memory.  I am running the 32 bit OS.  I hardly see the processor tick up to 1%.  The machine I am testing has about 300 registered endpoints in the proxy db.

My questions are:

1.       What is the scalability of ser processing calls?

2.       Are there any limits on the number of users that can be registered at one time. Is the registration memory based and am I severely limited with 4GB of memory?

3.       Is there anyone that has 1000s of registration to the proxy and if so I would like to hear how you are scaling it. What type of server are you using?

4.       What are some good metrics to look at on the sip proxy to gauge its performance?

5.       Is there a way to capture calls per minute?  Is anyone doing this?  I have call accounting set up.
