Squid configuration is not optimal ?!

Considering the following list I supposed that my cache is not really
that I could say excellent. The percentage of Tcphit versus TcpMiss is
disappointing.
The size of the cache is 1 Gb for let's say 15 constant users per day.
They have
Internet access for 12 hours/day(9-21) and ftp is denied. I should say
that this clients
visit daily mostly the same sites. And nothing fancy where the caching
to be denied.
So, in my opinion the daily traffic which is about 130 Mb is to much
considering the
above aspects. The possibility to somebody go around the cache is zero
since the
firewall is redirecting any 80 port traffic to squid 3128 so if somebody
try to use a
browser without using the proxys parameters the result is time-out.
If some of you guys want to "explore" a bit my cache and help, I would
be glad to send more details.
Thanks
