For those who are interested, here's some comparison data from CICNet. I 
turned on flow switching on our 7513s, for much the same reasons Sean 
did. This is from dgc.cic.net, one of our Chicago hub routers. It has 
moderate amount of traffic passing through it, about 20mbps over its FDDI 
at peak time.

Hope this helps,
