So I use the SMP but I have phisically 2 CPUs. I don't use HyperThreading. When I ran into this problem the CPU usage was not too high. The load was low and I had 25-50% idle CPU time (top). If I make some load on the macine the ping times grow and none else change. I checked that the ksoftirqd is not eating my CPU. In the next 2-3 weeks I'll try to make a setup with HFSC not HTB maybe it will help (I cant use CBQ on this machine). But there are about 20-25000 tc objects on this machine and it's not a 5 minutes job :-( I haven't any else idea yet :-( Arpad Kunszt _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
