[asterisk-users] Scaling Asterisk: Dual-Core CPUs not yielding gains at high call volumes

[Marco Mouta]

FYI,

http://www.voip-info.org/wiki/index.php?page=Asterisk+FAQ

*Can i install Asterisk on a beowulf cluster?* A cluster can't migrate
threads that use shared memory. Asterisk uses that kind of threads.So no,
Asterisk wouldn't work on a cluster. *(It might be helpful to know whether
anyone has a working load-balanced Asterisk configuration where multiple
systems can share the load of an Asterisk environment (IAX2, not SIP) and
whether this environment would fail over nicely in the event of downtime!)*
