Subject: [LARTC] filter performance/optimization questions

hi

i'm using htb + u32 filters, and i was wondering if there is something one can
optimize at this stage. i have a lot of filters (~ 50.000 / interface, and
there are two interfaces), and around 4500 classes / interface. the traffic
going through this machine is something around 210-230mbit/s at 50kpps.
as you can imagine, the load is pretty high. in fact (as it's a dual xeon at
2.4ghz), one CPU is always at 100% when the traffic increases.

i did some tests with esfq (that brought down the classes to around 150), but
the filters remained, and the load was still 100%. and i get some packet loss
because of that. not much, around 1-2%, but it's enough :)

is there something i could do to bring the load down? short of replacing the
whole system? i didn't find anything performance-related on the net, or in any
documentation.

thanks.
