This thread is resolved. Here is a description of the problem and solution.
Problem: I have a slider View that takes 30 seconds to preload 5 slides. How can I speed up the performance of Views pagination?
Solution: Counter-intuitively, some server environments will perform better if preloading is turned off for paginated Views. This is because of how Views handles preloading pagination by initiating one AJAX request per page. If multiple Views use preloading for multiple pages, the server response times can slow down.

Hi, Views preloads content for sliders per page, per slider. So if you're loading 3 pages (current, next previous) of content for 2 sliders, that's 6 separate AJAX requests happening at the same time. It looks like multiple calls to admin-ajax.php to preload content are slowing down your server response times considerably (see the network analysis screenshot). Have you tried disabling preload for the sliders on this page? On some server environments, this can greatly impact performance of these AJAX updates, speeding up the overall performance of slider pagination. Edit the View, then in Pagination and Slider Advanced settings, uncheck "Pre-load the next and previous pages - avoids loading delays when users move between pages".
You can also try setting different timers on each slider, to help stagger the initiation of AJAX loads.
