Yesterday's perf best-practices are today's HTTP/2 anti-patterns

Tuesday, 5th – 3:20

The limitations of HTTP/1.X forced us to develop various application workarounds (sharding, concatenation, spriting, inlining, etc.) to optimize performance. However, in the process we’ve also introduced numerous regressions: poor caching, unnecessary downloads, delayed execution, and more.

HTTP/2 eliminates the need for these hacks and allows us to both simplify our applications and deliver improved performance – a rare combination! In this session we’ll take a critical look at how the current best practices came to be; the new features of HTTP/2 that make them obsolete; and what you need to do to deliver the optimal HTTP/2 experience:

• Why you should unshard, unconcat, and unsprite your assets
• Why you should switch from inlining to server push
• What to look for in an HTTP/2 server for optimal performance
• What new best practices are possible with HTTP/2

… plus other hands-on tips for getting the most out of HTTP/2 both on the server and the client.
