Hello Heather,

Unfortunately, synthetic tests tend to provide lower or even bad scores for dynamic content like a slider. For example, apple.com scores terribly on mobile devices, while youtube.com scores also a very low value. These links point to the home pages that use static content for the most part. A highly dynamic page with videos and animations would receive even lower scores. It's easy to see that these performance measuring tools aren't too reliable when you test fast and trusted sites that also receive bad scores. While it can be useful, the results need some expertise to filter out false positives.

Still, we offer many performance-related options, including many that PageSpeed Insights recommends. You can find these under Plugin Setting's Performance menu.
