Well, it got a little annoying. I did a few tests with two types of configurations in /etc/nsswitch.conf 1) it is either hosts: files mdns4_minimal [NOTFOUND=return] dns or 2) hosts: files dns
I also have the following in the /etc/resolv.conf : #long lookup options single-request # Generated by NetworkManager nameserver 192.168.1.1 #long lookup options timeout:1 Sometimes even a simple google search can hang up for a while. However, one of the slowest sites I noticed is cnews.ru . I am attaching tcpdumps below. The command "tcpdump -n -i wlan0 port 53" is used here.
