Jim,
That statement bothered me, because we are running Asterisk on a
multi-processor system to help accomplish our scalability goals. I did
some double-checking on it by talking to Matt O'Gorman of Digium. Here
is what he had to say:
"Asterisk makes use of both processors for 99% of things. There are
some things like IAX parser or SIP parser that only run on one thread
(although Mark [Spencer] recently did multi-threaded IAX), but the heavy
stuff like each call spawns a new thread and Linux being awesome like it
is will share the load across processors. I mean just run top, you will
see load should be fairly balanced."
On our production server we are currently handling ~90 concurrent calls
with digital recording via Monitor as well as ~200 dynamic agents logged
in. top shows us running around 80% idle with processor 0 hovering
around 70% idle, and processors 1, 2, and 3 around 85%.
Your VMWare idea is very interesting, but I think it's unnecessary. I
believe that Asterisk *does* perform better with HyperThreading/logical
processors disabled.
