[c-nsp] ip route-cache

[Stephen J. Wilcox]

they're all variants of fast switching and you must use some form of it. netflow 
is cool but if you're not going to use the data that is exported you may as well 
not have it enabled and save your cpu cycles.

forget the routes. its about the actual switching of traffic from interface A to 
interface B. with fast switching disabled (no ip route-cache/no ip cef) the 
router will process switch each packet and you will not get very high throughput 
before the cpu maxs.

as i say, always enable it!
