sorry for the last emails kindly ignore that. i am not very senior in linux but recently i deployed squid and replace the ISA Server 2006. i was facing the same thing. the solutions, which kinda resolve the issue for me (for now) is. 1, DNS caching (powerdns) 2, reducing destination block list. previously i was using 2 MB destination block list for blocking chat and social sites in office hours. which was quite a huge list and i was unaware of that. and one more thing you can lookinto blocking youtube or video streaming if limited bandwidth is a problem.
