Subject: htb parallelism on multi-core platforms

Hi,

I'm using htb on a dedicated shaping machine. Under heavy traffic (high
packet rate) all htb work is done on a single cpu - only one ksoftirqd
is consuming cpu power.

I have limited network stack knowledge, but I guess all htb work for a
particular interface is done on the same softirq context. Of course this
does not scale with multiple cpus, since only one of them would be used.

Is there any (simple) approach to distribute htb work (for one
interface) on multiple cpus?

Thanks,

Radu Rendec
