If you go to https://www.chapelhillcreamery.com/our-cheeses, the page will show quickly, however for the first 3-5 seconds scrolling will stutter and clicking on linked images won't work, as if other things are still loading in the background. Eventually the page is fine, but then if you click on any of the cheese pages, a part of that page will load but will freeze up. Orion itself is fine and you can scroll down, but it will take about 3-5 seconds to completely load the page.
Going to one of the cheese pages directly, for example https://www.chapelhillcreamery.com/product-page/danziger, will show the page instantly, however for the first 3-5 seconds if you scroll back and forth you can tell it is stuttering.
