delayed http on ASA5505

Hi,

I have recently replaced a netgear firewall for an ASA5505. Below is my config.

My problem is that when I browse the web from my linux box, anytime I hit a new site, it seems to take about 30 seconds to a minute to do the lookup required to get to the site before I can actually download the web page. The DNS entries are correct, so I don't really know why else it takes so long.

Anyone have ideas? I've this problem so long it's driving me nuts. Even TAC couldn't help me out.
