I'd recommend you to look into bandwidth control to limit the amount
of bandwidth a single user may use, giving users a relatively large
initial pool size, but a slow refill factor. This will make downloads
slow down significantly without affecting browsing or messaging.

See delay pools in the Squid FAQ.

Won't help for this small traffic rates.

Another NIC only helps is your NIC is saturated with traffic.

Yes, but I do not think this will help either. Your problem should be
the use of the MAN link, not the proxy server.

Might help a little, but probably not very much. The main goal if this
would be to reduce the traffic between the branches and the main.

First make sure you have a clear indication of exacly what the problem
is.

From your message I am guessing the main problem is the load on your
MAN link, not the proxy performance. Because your MAN link is heavily
loaded the proxy performance appears bad. But this is only a guess.
