RE: WAY OT: DFCs vs CFCs with service modules

Considering these

> FWSM or ACE

Have a 5 Gbps bus speed, either of these cards could oversubscribe them quite easily.... so if the CFC is 20Gbps (If I recall) aren't we asking which
.500 Magnum or .50AE Beowulf pops a water balloon better?

Subject: OT: WAY OT: DFCs vs CFCs with service modules

All,
        Does anyone have any good docs on DFC performance gains over CFCs
specifically when associated with service modules? I have a setup where 80%
of my inter-VLAN traffic traverses either an FWSM or ACE. Not port to port
directly where the DFC seems to be geared. I have found plenty of docs on
CCO about the improvements in forwarding with L2 or L3 traffic but they are
specific to traffic that doesn't need to be processed by an on board
service module. Anyone?
