Thirded - we run our (currently 3.0.15 going to 3.0.17 rsn) servers with 4 GB RAM - the Squid process as we have it tuned and compiled never needs the extra 2 GB, but the system performance including disk caches is noticeably higher with 4 G than with 2. -- -george william herbert george.herbert@xxxxxxxxx
