Is there such a thing as too much disk cache? Presumably squid has to have some way of checking this cache, and at some point it takes longer to look for a cached page than to serve it direct. At what point do you hit that sort of problem, or is it so large no human mind should worry? :) Paul IT Systems Admin TNT Post is the trading name for TNT Post UK Ltd (company number: 04417047), TNT Post (Doordrop Media) Ltd (00613278), TNT Post Scotland Ltd (05695897),TNT Post North Ltd (05701709) and TNT Post South West Ltd (05983401).
