[Asterisk-Users] Performance: Xeon or Opteron?

[Rich Adamson]

I'd have to guess that combination of cards with almost any mobo would 
be considered an overloaded system. If you replaced the two TDM04b cards 
with an A200D or TDM2400 card, most of those irqmisses (etc) would 
probably go away; but that's a somewhat educated guess on my part.

Factually, the sangoma cards integrate with the pci bus in a much more 
stable/usable way then does the digium TDM card (and I believe the te110 
if it uses the TigerJet pci chip).
