[Users] OpenSER dimensioning. How many calls/sec can it set up?

[olivier.taylor]

You are right, of course, but that doesn't w-tell me what processor has 
been used for the previous tests.

If if was a double xeon(64 bits), 3.2Ghz, raid disks 8Gb memory, it 
means I better to buy a more than decent machine for 30 calls/seconds :)

kind regards,

Olivier
