Filtering in a 3640 is totally done by the CPU. Your 100Mbps uplink combined
with filtering is stretching the capabilities of the 3640 to the limit. BGP
also consumes CPU fast. So the only advice is (if you want to continue
transparent proxying) is go for 7000 series. Go for the fastest CPU module you
can afford. Filtering/redirecting on 100Mbps will require loads of CPU. I also
guess you want to be able to grow?

  Did you know that dolphins are so intelligent that within only a
         few weeks of captivity, they can train Americans to
       stand at the very edge of the pool and throw them fish.
