[squid-users] Part of Page Loading Slowly

I'm having an issue with a new squid install. Squid has always worked
fine, but I moved squid to a new server and am having issues. My squid
config allows access to 1 website for ordering purposes. Since moving
to the new server, when accessing the website, a certain page load
takes anywhere from 5 minutes to 10 minutes. Basically, the border of
the page loads, but the center of the page is some sort of ajax and a
scriplet form and that hangs. When it eventually starts to load the
form, it loads about 1 line per second and about 50 lines. When I
don't use the proxy and browse to the site, the page and form loads in
about 3 seconds. The whole time when it is trying to load, I get the
following when running tethereal on the server over and over until it
finally loads:

1204576907.204371 192.168.1.100 -> 10.20.30.40 TCP 59770 > squid [ACK]

On the previous server, I didn't have any problems, and I copied the
squid.conf over to the new server, editing the IP address and server
name in the conf file. The new server has a cable internet connection
several mbit's in speed. I even tried the exact same version of squid
on the previous version, but upgraded to squid-2.6.STABLE6-5.el5_1.2
without any difference. It's a pretty basic config, and the only thing
that has really changed is the centos 5 server that is now acting as
the proxy server and the internet connection is now cable. It almost
looked like some sort of MTU issue, but I've tried browsing the site
from a computer using the proxy that is on the LAN behind this server,
( this server acts as the gateway for this LAN).

Any insight would be greatly appreciated. Thanks.
