Hard to say without testing it, but if your estimate is reasonable (could you expand on how you arrived at it? there are interested eyes) then you max out at <5Mpps, which is not core-class routing this year, but is certainly within shooting distance of Juniper's entry level. Without any proper grounds for the notion, I also suspect the ia64 might do fairly well at fast packet classification.
