You're going to see more CPU usage. As I recall, when I reached 60k pps (on a single interface) my CPU would really spike and control-plane functions were sluggish. I am subject to microbursts as well.

Personally, I think you need to move to silicon. I purchased a pair of ASA1002's, have been pleased with them and my 7206vxr as well as my 7301 are on the test rack.

I am currently running a Cisco 7206vxr with NPE-G2 and 2GB.  I am peaking at
200M of Internet traffic on one of the GigE ports with 40K pps aggregate.
CPU over the last 72 hours looks like the following:

I am running BGP and taking 2 Full Routes from 2 different providers.  I
also have 3 OC-3's and 1 DS3 connected to the router.  I am looking for what
router I should look at upgrading to or if there is plenty of beef left in
this one?
