dual support yes.. however i read a few articles on the fuct that single with double the ram is better.. something about the bus or sshare between both processors i think. i would go AMD opteron, but that me. or sun On 6/13/06, Jon Sch?pzinsky <jos@detele.dk> wrote:> > Hello > > Is it correct that IAX2 uses more CPU, than SIP?

I use IAX2 quite a bit and I haven't really noticed any difference between
IAX2 and SIP. CPU usage in Asterisk is aggravated by transcoding, changing
one audio format to another, and SIP or IAX2 is simply the protocol used to
carry the audio. Any function of Asterisk will be affected by high system
load; if you have a loadaverage of 3, for example, your box is in trouble
regardless of the protocol used.
Although this may have changed in the newer 1.2.X series of Asterisk, I
believe that Asterisk does not support SMP from the perspective of
dispatching *internal* processes to different CPU's, instead, *external*
processes such as AGI's are balanced out and dispatched automatically to
different CPU's - but this is a kernel thing.
It's generally well-known that a "fake" SMP machine such as a
HyperThreading
CPU affects Asterisk negatively, and best practice is to disable
HyperThreading. However, "real" SMP machines have no trouble (I use a
4 way
Xeon). It's possible to "pin" a process to a specific CPU, and in
fact, I do
this to force Asterisk to it's own CPU, and pin all other processes to a
specific CPU that Asterisk does *not* use:
setasteriskaffinity.sh:
#!/bin/bash
ASTERISKPID=`ps -A | grep -a -A0 "asterisk"`
taskset 0x00000003 -p ${ASTERISKPID:0:5}
This "pins" Asterisk to CPU # 4 on a 4 way system. Repeat for all
other
processes, to different CPU's with the affinity mask:
0x00000000 = CPU 1
0x00000001 = CPU 2
0x00000002 = CPU 3
0x00000003 = CPU 4

Subject: [Asterisk-Users] IAX2 Vs SIP cpu load
Hello
Is it correct that IAX2 uses more CPU, than SIP? Also, can it be true that
IAX2 is much more sensitive against high CPU loads?
Also, does Asterisk support and use multiprocessor architectures, such as
Xeon?
?
Regards
Jon

There is work by the devs to threading in the IAX and SIP channels, I believe. I don't know if it's made it's way back to -HEAD or not, maybe kpf can give a definitive answer. I remember reading something by Mark S earlier this year that he had IAX threading working. -----Original Message----- From: Dinesh Nair [mailto:dinesh@alphaque.com] Sent: Tuesday, June 13, 2006 9:47 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] IAX2 Vs SIP cpu load On 06/13/06 22:49 Colin Anderson said the following:> Although this may have changed in the newer 1.2.X series of Asterisk, I > believe that Asterisk does not support SMP from the perspective ofisnt asterisk multithreaded ? on a proper OS thread implementation, threads can migrate across CPUs, can't they ? -- Regards, /\_/\ "All dogs go to heaven." dinesh@alphaque.com (0 0) http://www.openmalaysiablog.com/ +==========================----oOO--(_)--OOo----==========================+ | for a in past present future; do | | for b in clients employers associates relatives neighbours pets; do | | echo "The opinions here in no way reflect the opinions of my $a $b." | | done; done | +=========================================================================+ _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
Hi, I have two asterisk systems that share voicemail on an NFS. I recently upgraded to Asterisk 1.2.9.1. After the upgrade, the voicemail gets cut out after about 5 seconds of recording. Any ideas on what might be causing this? __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com
