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.

1) hosts: files mdns4_minimal [NOTFOUND=return] dns
