Pretty much never short of changes to memory architecture, IMO. Frankly,
there are never enough cycles for deep packet inspection applications that
need to run at/near line-rate. Don't waste any doing something you can
avoid in the first place.

Microseconds matter. Scaling up to 100GbE, nanoseconds matter.
