New findings: Retail sites that use a CDN are slower than sites that do not*

*NB: Don't panic. Correlation does not equal causation. More on that later in this post. In our latest quarterly research into the performance of the top 500 ecommerce sites, we found that while 75% of the top 100 websites use a content delivery network, CDN usage doesn't correlate to faster load times. Sites that use a CDN take a full second longer to render primary content than their non-CDN-using counterparts. Today, I want to discuss why these findings aren't as surprising as they sound, what CDNs fix versus what they can't fix, and how site owners can ensure they're covering all their performance bases.
