Problem: I would like to understand more about the caching mechanism in slider Views.

Solution: In a slider View, caching pages stores the contents of each page in memory while the User remains on the current page. Pages are delivered one by one so one page of results requires one AJAX call, two pages require two AJAX calls, and so on. Caching does not store the contents of each page in memory across page loads or refreshes. When you choose to preload next and previous pages, an individual AJAX request is triggered for each of those pages when the slider initially loads. If multiple AJAX requests are causing the initial load time to be unreasonable, I would consider turning off the Preload next and previous pages option, and/or the caching option. This will cut the number of AJAX requests that must be completed before the first page can transition to the next page, speeding things up at first. However it may also slow things down during transitions between pages later, so it's a bit of a trade-off.
