Hello, Websitedude1985,
1/ Typically, there is no such issue, however, in your case it is a specific situation with server requirements.
2/ As all these features use Ajax technology, which in turn makes requests through admin-ajax, the more of these elements there are, the more requests will be made.
Some requests are only executed after certain manipulations, for example Quick View sends requests only after pressing the button and search as well.
Some work without a trigger due to their particularities, for example, Ajaxify Widgets performs requests when an element is visible on the screen. The same applies to Wishlist For Variation Products, as a request is sent immediately after the products are loaded to determine which variation is selected and which one to add to the wishlist.
Kind Regards,
