Pardon, are you asking us if our squid is properly set up? It seems so, but
although I think there is no problem with it, you should NOT use "all" acl
to specify your clients. use "mynetwork" or so and define acl back as
"src 0.0.0.0/0"

Are you asking us if you can tune it a bit more?
Yes, you can. You can use much more space - for 64 GB of disk space try:

cache_dir aufs /usr/squidcache 50000 64 256

you can increase maximum object size:

maximum_object_size 32 MB

and use heap LFUDA replacement policy:

cache_replacement_policy heap LFUDA

I hope you configured squid with heap removal policies and async IO allowed

You don't need to tune these unless you use diskd. But on solaris, aufs
should be even faster.
