squid proxy server problems with 1 site

I’ve got a squid proxy server 2.7 on an Ubuntu 64 (10.04.02) server.   4gb ram, plenty of drive space…

It runs all of my 200 users just fine… Except for 1 site.
When I go to the site below, it comes up in a browser (IE), then just dies after a few navigations.  
When I remove Squid proxy from the equation, the site is slow, but not horrible.

When using squid, I get the site, click a few links then it seems to time out.

Any suggestions on improving performance?  Is it squid or the site?


Thanks

Here’s the site:
http://www.natlallergy.com/


The site is heavily cross linked with marketing crap.  I don’t manage the site, just some of the infrastructure in a my call center.


I see some high load times  in access.log:

It seems that your squid server is waiting for some sort of timeouts - 2 minutes for the first request and 1 minute for the last request.

This could be a number of things including DNS timeout (for example remote server not responding to a AAAA record request, only after the timeout the A record is requested)
