I have an ADSL connection with a Linux router. As soon as someone
pulls something down through my link it saturates my slow 128kbits/sec
upstream link. Then all downstream performance on my fast 1.5mbits/sec
downstream link goes to hell. 2 seconds to ping the gateway, horrible
web page loads, etc. I'm trying to solve this problem in a simple way.
My understanding is that this is a well known problem with assymetric
hosts - the queue for the upload is blocking ACKs and SYNs and all
those useful things from getting through the upstream link. My
understanding is also that using fair queueing on the link would help.
So I grabbed iproute2, built the sch_sfq module, and installed it with
tc qdisc add dev eth0 root handle 1: sfq
However, it didn't seem to help at all.
Am I wrong in hoping that SFQ will help my problem? Or have I
misinstalled the scheduler somehow? The iproute2 documentation is
quite hard to puzzle through, even for someone who has some clue about
routing.
I promise to document how to do what I'm trying to do if someone can
help me figure it out.
Thanks!
Nelson
