[c-nsp] IOS SLB on a 3662

[Paul Stewart]

Yeah... I think it'll kill that router... Just my opinion

The only comparitive I can provide is a 3662 I have in production right
now running IOS SLB with NAT and it's only pushing about 3000pps or 12.5
Mb/s and the CPU sits around the 45-55% range.... 

Hope that helps...

I'd suspect the worst case is 10k concurrent sessions - we're running
rather lower than that just now.

In terms of PPS, given that all we'll be doing from behind it is HTTP
redirects, that translates to around 10kpps assuming standard ethernet
packet sizes. I know this is close to the process switched limit for the
3660
(12kpps) but I've no idea how that scales against SLB usage.

At the moment we're doing closer to 3k concurrent sessions as a peak.
