What exactly does the CPU speed on a router affect? General throughput, streaming audio/video, downloads, the number of users, something else?

Any info on this is appreciated. Link to docs are acceptable as well but would prefer a summary.

Iam speaking of any router from a Cisco to a freesco (http://www.freesco.org).

Regards to all,
John

CPU will affect how quickly the router routes. Routers are traffic managers. When a packet comes to a router, the router will/should 1)know all network addresses 2)How to connect to other networks 3)The possible paths to other networks and 4) The costs of sending data over each path. The router should eventually send the packet over the fewest hops/costs. The CPU will afffect this whole process. If you are in a heavy-trafficed network and have a router with small CPU...this may be a cause for slow WAN traffic. Obviously bandwidth can also be a problem. Hope this helps!
