Well, I would check the HTTP response headers there. Make sure they are
containing Content-Length: header. If that is missing Squid is forced to
assume it will have infinite length and require disk backing for the
object until it is finished arriving.

The "Mean Object Size:" metric is measured on completely received and
stored objects. So does not really account for unknown length objects or
non-cacheable previous objects.


Please be using
  Current Stable Squid 2.7.STABLE9 or 3.1.14
