At the low end it's acceptable. Gigabit traffic sucks on 7500 series routers even without any kind of filtering. The 7000-series routers, if they have an SSE, will do standard and extended access lists in the switch engine. Now, given the limitations of CX-FEIP-2TX boards (the only faste boards that will work in a non-RSP 7000), you are lucky to get 70 mbit/sec through that. If you have fddi, you can get most of the way to 100 mbit/sec one way (the CX-FIP cards, which are the only FDDIs that work in a 7000, won't do full-duplex). The 7500-series routers, you really want to get a VIP2-50 rather than a 2-40 or lower if you're going to be doing filtering on the linecard. You can load the fast ethernets up just fine there. 400 mbit/sec seems to be the upper limit of the currently shipping generation of gigE cards for the 7500 series. Hope this helps (and standing by for corrections from the #cisco IRC mafia...) ---Rob
