[asterisk-biz] Performance on Pentium Dual Core CPUs

[Tomer Horn]

I'm curious if anyone is running Asterisk on Sun Fire T2000 or similar 
UltraSPARC T1 servers.
Or maybe generally running Asterisk over Sparc in production environment.


Anyone? Any comments about performance using Sparc?

In addition, when Digium releases the hardware G.729 transcoder board in the near future this will become less of an issue for deployments of that size.
