Did you test after using the automatic partitioning of your
main-server?  Without a separate partition for the squid cache, the
proxy will use very little disk space and thus have a very small
cache.

I tested today with my main-server, and the PXE installation used the
proxy and almost all the packages (not the updated debian-edu-config,
which is good) were fetched from squid and not from the remote APT
mirror.  I got 75 Mbit/s when installing, while the first installation
filling the cache had 40 Mbit/s. :)
