Hi Some time ago I said I am going to install hash tables to optimize a high load cbq machine. We did it and now the load on that machine doesnt pass 0.5 when usually it was arround 10.0 :) We used a single hash filter which reduced the amount of comparations for each outgoing packet from an average of 1000 to an average of 10. Hash tables rules ! ---------------------------- Mihai RUSU Disclaimer: Any views or opinions presented within this e-mail are solely those of the author and do not necessarily represent those of any company, unless otherwise specifically stated.
