asterisk users - Sep 2005 - is a dual 1.5Ghz server better than a single 3Ghz for a 100 Iax users asterisk server

Hi everyone,

I'm looking to buy a server that could handle 100 IAX users (g711)-(about
300 registrations) simultaneously.
No zap channels.
My budget is 1000$ us,

Is a fast (3ghz) single server more reliable than a double cpu (like 1ghz) ?
Will asterisk take full profit of two cpus?
Isn't better to get a second cpu to handle system processes (like stat
generation, backups...)? so that the remaining cpu will always be free for
asterisk?
I have also a 500$ deal for a 4 pentium III 500 cpu server.



Thanks,

One key that I have found is the more RAM the better. I am not discounting
the CPU by any means and with the number of registrations you are talking
about, I have not set up a system for that many concurrent users.

I do have a 2x1.266 PIII w/ 2 Gigs of RAM that handles 75-85 concurrent SIP
(GSM) sessions + 3 IAX2 trunks for a total of about 100 calls at the same
time. (Using * 1.0.9). I also have this server set up for a file server
(authentication using LDAP in a Win2K ADS domain).

I also have a Celeron 1Gh w/ 2 Gigs of RAM that handles 72 DIDs, 24
connections to our traditional PBX, and is our incoming FX server. (Also
running 1.0.9)

Many, if not all, of our issues seem to "go away" when the server a)
has
plenty of RAM (IMHO, max the Ram!) and b) I schedule a nightly reboot.

Just my 2 cents.
