It's very consistent too - I downloaded a 4MB file several times with fetch, and several times with wget, and on each TCP_HIT it took 3 minutes 25 seconds, which wget reports as 20.01 KB/s. As I said before, I'm pretty sure that something has changed here. When I first setup squid, a few months ago, cached images were loading instantaneously. It's pretty hard to say when it changed because my large downloads don't go through squid, and 20.01 KB/s times several connections simply makes a cached page look like an uncached page.
