I use the CPU as timer and I have a dual Xeon box. 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 :-(
