I, are you sure about the big difference?
I agree with you about tc u32 filters are better than iptables +
marking, but like now I have about 100mbit 1k+ users with
mangle+classify and tc+htb+egress and I have a load at about 0.2.
My cpu are xeon 2.6 quad.

In my experience, instead, I see that nic can make big differences about
throughput
