Sounds good, but that's not really what I meant.
My question is: in my scenario (nntp traffic lowest priority, all other traffic normal, processor PIII already straining to keep up with the traffic shaping (35% when there's a lot of nntp traffic)) which ones should I check? I guess there's a trade-off somewhere between processor power and extra methods checked.
Can anyone shine a light on this? I can read about the theory but I would like to hear some practical experience.
(Again thank you Setsun for your help!)
