I've been Googling around for some time now (a few hours on dial-up).
I find all kinds of questions similar to mine, but either there is no
answer or the answer has nothing to do with the question. Hopefully
this post isn't another one of those.
Does Asterisk favor FPU performance or clock speed? (Meaning AMD or
Intel)
In this instance I think you're asking the wrong question. Asterisk
will scale better on a processor that handles branching better, so the
AMDs with the shorter pipelines will help here a lot.
I see Asterisk can be compiled for x64 systems. Does it run any
better\worse on x64 versus i386?
I have heard good reports from x64 systems. Especially the AMD variety
that isn't drain bamaged.
Dual-core CPU performance isn't as good as dual CPU's, but is more
often than not a better deal as it's close, but a lot cheaper.
Dual-core vs. Dual CPU performance depends on the application. How
does Asterisk respond?
Looking to build out a system capable of 100 concurrent calls (IP
pass-through, so in effect 200). Looking at the dimensioning, I can
get some ideas, but few of them state the call quality. I'm hoping to
be able to use a single CPU that is dual core as the price to go to a
dual CPU that is single core puts me at least 60% to a redundant server.
Asuming no AGI, a single p4 will handle 200 calls.
More information about the setup
------------------------------------------------------
No cards of any kind (Tyan board with integrated video, NIC, SATA
nothing more needed)
some IAX2 trunks (ztdummy)
mainly SIP clients, but an increasing number of IAX2
mainly ulaw\alaw, if not solely (the transcoding chews CPU cycles
needlessly)
