IAX2 very CPU hungry

Hi!

Just changed the protocol when P4-3Ghz (1.2.12.1) box have 
been dying receiving 60-IAX2 with 100% load of asterisk 
process, and changed the protocol to SIP - Load decreased 
to under 50%! So seems implementation of IAX2 far no so 
good as SIP implementation. Any hope to get IAX2  better in 
1.4?

Hi,
it really is a lot better in 1.4. 

Best regards,
Loic Didelot.

Do you have turned on hyperthreading?
Codec is alaw or some compression?

That true for PC both with with HT or P4-D (though P4D has 
better performance.) No compression, ULAW. In any case SIP 
eats MUCH less CPU than IAX2

Another thing to consider is do you have sip re-invites
turned on.  This
would keep sip calls from coming back to the Asterisk server
by letting the
RTP Streams go directly from phone to phone.  Not sure if
IAX2 has this
functionality, as I don't use IAX2 due to I'm only
supporting Cisco and
Linksys IP Phones.  Something to think about.

One of the things that Asterisk 1.4 added was a
multi-threaded IAX
implementation (thanks Mark!).  From the little bit of
testing on it
that I've done, it's made a huge improvement on how well IAX
works
under load.  Check out the "iaxthreadcount"
setting in iax.conf.
