I don't think you should modify refresh_pattern nor play with
reload-into-ims to have better caching. Squid caches the content good
enough without playing with these options.

It's good. However, much better would be using dedicated disk for squid,
because you can expect high load on the disk.

what do you want to achieve using this config option?
I don't see the 'lan' acl in config below.

Please read the squid FAQ, especially memory needs.
Squid will hold much metadata in memory, for 70GB it
would be much much more than 120MB, not counting the 96MB for cache_mem.
on 512MB machine dedicated to squid and iptables, I'd let squid use up to
384 MB of ram (high_memory_warning 384 MB).

But our proxy with 2510349 files (~30GB of data) causes squid eat ~256MB
on startup, so you can expect double that ram for metadata only. So you
should either decrease cache to ~20GB, or you should at least double your
RAM, "reserver" 128MB for OS and the rest and use that number for
high_memory_warning. After a week you will see if you can set the
cache_mem higher.
