No more than a couple times the per-user refill rate but not
less than 4KB.

You will have to assign a larger pool size and then rely on Squid to
distribute the shared bandwidth evenly when there is congestion for
the available total bandwidth. The intention is that Squid should
distribute the shared pool pandwidth somewhat even between your
active users, but as always there might be room for improvement.

I would also recommend investigating the effects of using a larger
bucket size, allowing for burstiness. This way you can make sure that
web surfers get a somewhat reasonable bandwidth, while downloaders
are limited. By using a bucket size larger than the refill rate you
can make the limit an average over a longer timeperiod than a single
second at a time...
