About those IRQ request issues, i wrote something about that today.

http://www.asteriskguru.com/tutorials/pci_irq_apic_tdm_ticks_te410p_te405p_noise.html

Some part in there also mentions assigning an irq to a different cpu.
This should help with people with interrupt issues (or multiple zaptel
cards in one machine).

If it helps for someone, let me know, if it doesnt, let me know too.

Good questions I have always wondered about since I have a DP box for my

Isn't that only true in the event that no transcoding is happening?
Won't processor usage increase pretty drastically if transcoding occurs
a lot?
How about if the users have music on hold a lot or use a lot of MeetMe
rooms?  Will that increase that processor use as well?

Also. Does the presence of a second processor help with IRQ request
issues?  (sorry if that question is really dumb)

Thanks,
Wiley

Telephony doesn't use a lot of processor. We think one of the principal
arguments for a second one is that you have another processor in the
unlikely event that your primary fails.

Subject: [Asterisk-Users] Asterisk's MultiProcessor Ability

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 dristributed
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?
