Erm, that seems kind of low. Flow volume for two 6509s in what I consider
a small to medium size hosting site, with about 6+ gigs of differentiated
egress generates more than 8 to 9 *thousand* flows per second, and that's
after discard incomplete tcp flows (port scans, half open syns, etc.)
Are you sure you're getting everything?
