filtertesting.wpengine.com is a site with a large catalogue 20k+. We’ve noticed something odd with infinit scrolling, once you land on a category, only the first batch of products loads, as you would expect, but as soon as you scroll down and trigger infinit scrolling, instead of it loading the next batch of x products it starts to download all the items in the category, you can see the scroll bar changing as it does so. This is a major performance overhead.
