Burst is a good idea
Actually you need to specify burst and cburst for it to work and I
suppose the law doesn't stop you being more generous than 255kbit - I
just tried 100k (= 100k byte) and browsing isn't too bad.
Browsing and downloading together with just fifo is horrible though. I
tried htb with the prio qdisc and it was dissapointing WRT latency. HTB
class prio was far better. In both cases I also had sfq on the leaf of
the tcp class, which makes browsing while downloading nicer and for tcp
games didn't hurt latency too much.
I was only testing with one user though I scripted two, I'll get round
to playing with curl loader one day. There's bound to be a mistake
somewhere, but I paste below what I did. class/flowids are hex and you
have 0-ffff after : (minor) to play with - you'll need a more sensible
numbering system that I chose.
Policing was also not too bad.
