Comment 34 for bug 155393

Hi Christiansen, I see nothing in the two tcpdump outputs to explain the difference in speed. The DNS-releated problems that we think have been fixed by bug #156720 show themselves when trying to establish connections. You've a long running connection to a web server where you're downloading lots of data so I don't think it's the same cause. Plus, your dig lookups work fine all the time. So, although the symptoms are similar to this bug's title, I'd suggest it's a different cause and you'd be better off opening a new bug or trying to find an existing one, ask on the Ubuntu forums, etc. Does the speed change during the same connection, i.e. does `wget http://some.big.file' flicker between two download rates? Sorry not to be more help, but it's easy if each bug can be tied to one cause even if the symptoms are similar.
