Do you have ipv6 enabled ?  ifconfig...

Do you have cache settings {moz} set really large ?

If the problem is at all network based, then running wireshark, capture, 
and then  trying to load the page gives the answer to:
- how long till the dns is requested /responds ?
- is it waiting for ipv6 results ?
- which sites is it actually getting connected to:
- is that site fast.
