Slow Pages After Adding TLDs

[Positive and Grateful]

I'm using the Premium Comparison template, and I added a lot of TLDs to my WHMCS, and now when I go to this page:

/cart.php?a=add&domain=register

Or this page

/cart.php?a=add&domain=transfer

they both load extremely slow.

I've checked the community for similar issues,  and tried everything including deleting the price table and nothing changes the load time (still slow).

To avoid these 2 pages all together, I'd like to use the interface located here: /cart.php?a=add&pid=2  as the main Register Domain & Transfer Domain pages, the only problem is, this interface is part of a product setup process. Is there any way I can use this screen as the Domain Registration and Transfer screen without having it be locked into a product? Maybe by copying the code and placing it somewhere else?

Thanks in advance.

You could create some negligible product (even could be scheduled to terminate 1-2 days from purchase). Make the product auto-setup and no fees. and no description. 

But otherwise, you may want to consider using the Integration Code and hosting your own domain lookup interface outside of WHMCS.

Not a bad idea. I created a fake product, made it free, and checked off "Require Domain" and "Hidden".

The only problem is that it shows on the "Review & Checkout".
