Hi Michele,
  "extremely slow" is quite a poor indication, unfortunately. Can you
measure it? e.g. by using apachebench (ab) or squidclient to measure
the time download a large file and a small file through the proxy from
a local source and from a remote source. Then repeating the same from
the box where Squid runs and then from a different box.

Think about what has remained unchanged since when there was no
performance problems: e.g. network cables, switches, routers etc.
