Hi,

I'm sure some of you stumbled upon this one, but for those who haven't I
recommend this read.
It is a very good read on where different sorts of queues reside in Linux.

http://www.coverfire.com/articles/queueing-in-the-linux-network-stack/

The author covers a lot of ground including TCP Small Queues, Byte Queue
Limits, etc.
Also provides his own qos script and some interesting things like the fact
that txqueuelen is only used as a default queue length for *some* of the
queueing disciplines, not all as others have it governed by tc.

Best regards,
Maciej Soltysiak
