So I have a bit of a problem.

Scenerio 1

I have category pages that I can easily get a Pagespeed score above 95 if I only load part of the records on page load. Then, if the user scrolls down the page, more records that belong to that category load via ajax.

Scenerio 2

I can load all the records at once for crawlers to crawl but the Pagespeed score suffers into the 80s and 70s. The response time doesn't really suffer because I do a lot of caching of queries. What really lowers the score is the excessive Dom size. Listing all the records along with their thumbs can into the thousands of html elements.

​

So my question is, Which is better to sacrifice? Pagespeed Score or Displaying the full list of content in a page?
