[Asterisk-Users] Asterisk's MultiProcessor Ability

[niels at wxn.nl]

on the simultaneous calls asterisk behaves well on SMP sytems.. 

The problem could be in the many user-logon's per second you have (user
logons are handled in a single thread only) With about 1000 to 1500
IAX/SIP users online per box (dual xeon 3.2 ghz) we start expiriencing
problems over here .. One of the 4 processor threads goes to 0% idle

I don't know if the g729 lib could have something to do with it.

I use a Dual Xeon hyper threaded, top shows it as 4 cpus and the load
seems to be pretty well balanced.

We have asterisk running on a quad processor dell. The kernel has been
compiled with SMP.

However, asterisk seems to only use 1 processor. 3 of the 4 always stay
at 100% idle.

Is it pointless to have a multi-proc machine? I was going to buy a new
dual 3.6Ghz Xeon server but if nothing will take advantage of the other
proc...

Perhaps my conception of multi-proc/threaded is warped. If asterisk is
the only thing using CPU, I would expect the load to be distributed
amounst the processors. Instead of 1 proc falling to 20% idle (80% using
on that 1 proc), I should see all 4 procs fall to 80% idle (20% used on
each). Is this wrong?

What about the g729 library from digium? Is that multi-proc aware?
