  Not because of AS path info, definitely. Netflow does route lookup
anyway to get nexthop and route masks. If route lookup will return
a pointer to a structure with one more field it will not introduce
ant additional load.
  My experience shows, that most load in flow processing is caused
by: 1) memory allocation, 2) expiry lookups.
