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.
