Indeed.

   Whether anything can be done by Squid depends on whether the clients
using Squid are on the outside of that 12Mb line or on some faster
connection between them and Squid.

  For a faster internal connection and slower Internet connection you
can look towards raising the Hit Ratio' probably the byte hits
specifically. That will drop the load on the Internet line and make the
whole network appear faster to users. The holy grail for forward proxies
seems to be 50%, with reality coming in between 20% and 45% depending on
your clients and storage space.
