I used two different 7200's with the exact same results. Bidirectional throughput on 1GbE is a fraction above 10%. Unidirectional is a bit better (23%). Singl line ACL drops it to 8% (permit ip any any). FE performance doesn't start to drop below line rate until you put more than two in the box. I have a powerpoint if you'd like it, but it is not meant to slander Cisco, just to convince my customers NOT to put GbE in a 7200! It is not a GbE platform! > I'd say 300+ mbit/sec on a PA-GE is a more accurate real-world limit, > assuming you've got plenty of spare CPU cycles to burn, and no ACL's. > > Besides, that's really an apples to oranges comparison.

It is line rate with less than 7 us latency on the two GbE ports. I tested this myself. I can forward this to you if you like. It is a bunch of SmartApps screen captures of the testing. I really like the 7200 VXR. It is a good 10M and minimum FE platform. It can switch DS0 on the midplane and it supports a wide array of interfaces! I just don't like to see it oversubsribed. Many of our customers use the 7200 and have nothing bad to say about it when deployed properly. Gary
