        Is it possible that a single legitimate transfer from a user
saturated the link and slowed down other connections? For example,
somebody could be downloading a huge file or playing streaming media
through your proxy. If that is the case, you may want to look at delay
pools. The pools are designed to limit the bandwidth a single user (or a
group of users) can consume at a time. See delay pools description in
squid.conf and FAQ for details. (Note that negative byte hit ratios
are not necessarily related to this problem)

        If nobody on the list has a ready-to-use solution (I do not),
you may have to enable access logging to see what your Squid is actually
doing during when it is using all available bandwidth.
