Really?
We had Asterisk 1.8 with this setup and pushed 250+ concurrent calls
through it and it coped quite well. All these used local channels for
dialling.
Our new systems are Asterisk 11 with no Dahdi. Quad "Intel(R) Xeon(R)
CPU E5-1410 0 @ 2.80GHz" and reached about 40% cpu with 300+ concurrent
calls.
The new systems are a complete reinstall (OS upgrade with alter kernel
to take advantage of res_timerfd) but like previous versions they still
suffer from a gradual rise in load average. Every month or so we need to
restart asterisk to bring the load average down. No idea what the cause
is but its an automated process now so has no impact.
