I used sipp and the simplest openser config (just forward() ) and
couldn't get very good. It seems that the limitation comes from sipp.
You can try to use multiple sipp servers shooting at same openser to see
if you see some differences. CPU used by openser was insignificant when
the peak of cps was achieved.

bay area is about 300 call setups per second, and indeed, this
performance was achieved on a iPAQ, with 0.8.x about three years ago,
using the basic config file with no database backend.

the number of children is related to the number of interfaces openser
listens to and the type of transport protocol enabled (UDP, TCP).
what is the name of the opened unixsock?

Any backtrace?
