Re: [squid-users] 100% CPU when bigger files are downloading

I didn't change my config at all, so I'm fairly sure it's simply
updating to 3.3.8 that fixed it for me. All I did was change to Testing
and do apt-get dist-upgrade.

Maybe Debian compile it differently to Ubuntu - This is what Debian's
version tells me:
Squid Cache: Version 3.3.8
