based on my experience, the 3640 may not give you the performance you require. especially if you are using any access-lists, route-maps, QoS. Also, with your peaks at well over 100 meg, you might want to consider a gig interface on the LAN side. a thought - use a dual ethernet router like a 3745 ( twice the performance of the 3640 ) in combination with the switch ( which can easily handle the load ) put your servers into two subnets / vlans and do quasi-load-sharing across those two ethernet interfaces. depends on your traffic requirements.
