router metrics

["Steven J Lamb" <redhattedsheep@xxxxxxxxx>]

I am looking a way to determine how much CPU / memory utilization I will 
need for a machine that  I am using for a router. I am planning on routing 
about 10 Mb of traffic through this box and I would like to use some type of 
bandwidth monitor. On it as well. I know my question is kind of vague, 
however my question may be better phrased this way. how do I determine how 
much CPU/memory is used when I am only routing traffic. My intention is to 
use FC4 and iptables for my routing. Does any one know what kind of 
information I am looking for.

Thanks in advance
