Net connection is fast and wide, so gb should be ok. In that case another question for the list: Seeing as I'm not doing ANY caching at all and just proxying traffic are there any recommendations for squid.conf settings that might optimise my users' experiences (other than caching..). I have fast ACLs where possible in place and my squid.conf is as below. I'm looking for any tips on maximising memory, processes etc from within the squid.conf so that the end user has as quick an experience as possible - Are there any other tags I should look at using?
