DHCP WPAD and slow Internet Explorer page loads (SQUID Proxy)

We use SQUID Proxy (Symantec's CSP) in our environment. I have configured WPAD.dat on our DHCP and it is working successfully however, it is also often causing slow Internet Explorer page loads.  
 
So, if I configure the Proxy server settings within Internet Explorer (Local Area Network (LAN) Settings), Page loads are a lot quicker.
 
Any ideas on how to improve Page load performance using configured WPAD.dat through DHCP?

This is a problem with your DHCP server.
You can use WPAD over DNS instead, which in comparison is lightning fast.

Awesome! Do you have any information on how to setup / deploy WPAD in DNS?

If your AD domain's DNS name is say example.com and some department/subsidiary uses sub.example.com, it would suffice to add host wpad.example.com and put there wpad.dat file (or another wpad.dat in subsidiary DNS domain's wpad host if you look to override)

So just create a CNAME in DNS pointing to the server hosting the wpad file?

Client has to have the hostname in that DNS domain (99.99% true in a windows domain)
Configuration in client;s end is same as for DHCP WPAD - "automatically get proxy settings for this network"
