The traffic is 24Mbit max, average 20Mbit.
OK... What's wrong?
I can only use 4775 filters :/
This is a reslts of my small script...

I need more filters :/
I have 2.6.11.11 kernel with new iproute2, u32 match mark support and
IMQ (AB)...
Everyone can make theoretically 0xffff (65535) classes and qdiscs on one
device. And I think this is true, but I can't add more filters then 4775! :(
