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. -- Totus tuus, Glebius. GLEBIUS-RIPN GLEB-RIPEReceived on Tue Mar 02 2004 - 13:24:11 UTC
