Kinda hard to assess really, how long is a piece of string ?
You could, of course, count the cache hits, and multiply their size, by
their frequency etc ... but that doesn't really give an answer, as there's a
human factor ... bandwidth usage may well have _increased_ because you're
using squid (or any other cache), people will use the internet more often if
it's responsive, when it's not, they go back to doing things the old way !
The only real way is to turn off the cache for a week, keep stats, turn it
on and keep more stats ... and even that won't answer you !
