This session demonstrates practical techniques that drop a web page's size from almost 3MB to 143K, and load time from 6 seconds to less than a second, while looking the same! Review tools that validate and describe performance best practices. Explore how to defer resource requests, load resources asynchronously, and prefetch critical resources. Many other performance improvements will be discussed, which can reduce response time while also boosting the scalability and reliability of your site. Learn the techniques that can have the largest impact on web performance with the least amount of work.

You will learn:

• The proper techniques to always use, use only for HTTP 1.1, and use only for HTTP/2
• Discover tools to check websites for adherence to performance best practices
• See how to decrease the size of an entire web page to less than 1 image on original site
