what I'd advise you
- using LFUDA cache_replacement_policy (memory replacement policy may
  stay GSDF)
- using bigger cache (if your 700 kbps link is loaded with HTTP requests,
  your users are probably downloading more than 7GB per week)
- play with maximum_object_size and

another question is, if squid eats a lot of CPU and memory - unless it's
badly configured, it should not.
