Subject: htb parallelism on multi-core platforms
Date: Friday, April 17, 2009 - 6:40 am

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
