Good point. Thanks. 35mb both in and out. Plus a fast Ethernet doing the
same. Currently using netflow. I agree on the CPU. I'm looking into why
we are not using cef. Thanks.

When you say 35mb or 50-80mb is that total on the router over all interfaces
or 35/50-80 in/out from upstream and then 35/50-80 pass through to LAN ? We
are doing about 60-80mb in bound on FE from upstream and 60-80 in bound on
FE to LAN on one of our border VXR/400, 512mb and the CPU sits about 45% -
based on this you should be fine with a 400. Do you have CEF running ? The
CPU seems a bit high for the 300 currently with 35mb
