I have a transparent bridge proxy squid 3.x on a debian 6 box. It performs
extremely well for browsing, but it turns out very slow when downloading
sibgle files.

wget

but when I don't use squid the speed looks grown up 500K/s.

Any hint ? Squid for browsing are working very well.

Thanks for any help.
