ah ok, good :)

I just did another test with flowd only logging AS info and octets, this 
with the following results:

finished in 145 seconds
flowcount: 961501
6631 flows/s

twice as fast, but still much more slower than flowtools.

Great. I really prefer flowd, but I need speed. If I can be of any help, 
let me know.

thanks for the fast reply!
