I’ve finally put up a couple of example Squid deployments in the real world – Wikipedia and Flickr. They both use Squid as a web accelerator to serve a whole whack of traffic.
I’m looking for some information about current Squid forward proxying setups in the real world – we know that Squid’s capable of a whole lot more than people realise – even given Squid’s shortcomings it can push at least two or three hundred megabits on modern low-end modern hardware without trying too hard – which will save ISPs a whole lot of money even with modern bandwidth prices.
Let me know if you’d like to share your current setup and performance figures. We might even be able to help you make it faster!
