I executed your script on my router and I had no http timeouts. Everything
went fine.

You have a sfq qdisc attached to your parent class. That's not possible. You
can add the sfq qdisc, but if you add a child class, the sfq qdisc is

I looked at your tc stats, and I found it strange that you have negative
tokens and ctokens. But I don't think this is causing the http timeouts.
If you have these timeouts, is your link havely used? If yes, you can try to
prorize ACKS/SYN packets.
