I've for a little time had the problem, that it took a while for my browser (Chromium) to load websites. It says "Resolving host" for a while, and then eventually loads; but this process can be pretty long. (Usually up to 30 seconds.)
It's not always like this, sometimes it works fine for some time (usually about 10 minutes), and then it begins to do it again. First, I thought switching to OpenDNS would fix the problem, it worked on Jaunty that way (had the problem on Jaunty too, but fixed by switching to OpenDNS). Also, download speed works fine (about 500 kb/s, which is decent for the connection I have). The same problem occurs in Firefox.
Ping to google.com:

Also, it seems like when I loaded a page i.e. SuperUser.com, it can take those 20-30 seconds to connect the first time, but then I can surf around with normal loading time.
So to sum up: It takes a while to load the host (i.e. SuperUser.com), but then I can surf around on that page with normal loading times, once it connected the first time. Anything else works fine; i.e. Download Speed, Skype, IMing, online games..
Anyone got an idea of what could cause this?
Edit: Tried to reinstall Ubuntu, doesn't fix the issue.
Edit: Disabling Ipv6 Module gives a good improvement, but not perfect.
I have similar issues with Ubuntu 18.04. I haven't find a solution yet. – Mpizos Dimitris – 2019-12-03T14:33:58.780
2Sounds like a slow DNS server, have you tried with different DNS ? – ukanth – 2009-11-09T14:19:46.800
Can you recommend anything other than OpenDNS? – Sirupsen – 2009-11-09T16:40:07.397
To answer my own "question" about good OpenDNS alternative; Google just launched a public DNS.http://code.google.com/speed/public-dns/docs/using.html
