1) while your Squid supports large objects in rock stores you are not
actually using that. So your Squid workers are still stuck with only
the memory cache shared, and disk caches separate.

2) you have several different cache_mem values spread across the
workers. Only the last cache_mem matters so you have only 6GB used by
any worker. Not the 25GB you may think some are using.

3) you are doign similar things with minimum_object_size. But again
oly the last configured value matters. So its 0 for all workers.


The mean object size is just an average of all the cacheable traffic
your proxy is processing. Bandwidth savings is more closely related to
*total* cacheable traffic than an average of individual object sizes.
