access_log none
This is meaningful, when you don't want so many requests (1GByte per day).
You can activate access.log, when you delete this line in squid.conf.
Be sure, atm you can not control this access.log, when there are problems in squid you want to watch!

An important option for squid-2.6 and later is:
collapsed_forwarding on

This option combines requests agressively so that a file is retrieved only once from the origin server. This is a very good idea for computer farms so make sure it is on.

Have it installed in Squid 5.5 yesterday, no problems so long.

Post:
Why use frontier-squid instead of regular squid?

The most important reason is that with frontier-squid you get the benefit of many years of collective operational experience on the WLCG. The frontier-squid package contains configuration defaults and bug fixes that are known to work well with the applications used on the grid, plus some extra features in the packaging (see below).

Knowing not enough details for a squid, but
HPC (Highperformance_Computing) need some more experience and details for us to optimize this work for Cern.
Have TByte every month over ISP.
btw, my squid is running on my fastest PC.
CernVM is a idea to let CVMFS on the local network, without Squid.

Example from the night five Atlas (3 with 6 hours and two with 3 hours doing nothing, because of starting and get no right CVMFS connection!
It's time to find a solution for this!
