Good Morning all,
I have got a 2610 that is doing NAT between two networks.
We have performances problem and the CPU in the traffic burst reach betwenn 80% and 95%.
We have also available a 2621XM.
Before to strart the substitution of the router I'd like to know if it is worth to do it.
The performance for the 2610 are 1500 pps (for process switching) and 15000 pps (for CEF/Fast switching).
The performance for the 2621XM are 1500 pps (for process switching) and 30000 pps (for CEF/Fast switching).
I know the NAT is a process switching feature (all the packets are processed by the CPU), so I wonder if the upgrade will have any effect due to the fact that the process switching performances are the same for both routers.
Any links or on-line document available?
