Hello,

Multiple things can be done to improve the performance of S3. First, you can use Multi-Region Access Points to ensure the data is available in different regions with automatic failover. In addition, you can use CloudFront to host the website, redirect dynamic requests to the compute instances, and cache content at the edge, which will drastically increase performance. Using CloudFront, AWS will then automatically use the Backbone to send the request back to the user.
