Once upon a time early modems were slow. The broadband came along and web page byte count and code skyrocketed. Now? Now we have slowness even at broadband speeds due to page bloat. And if you're on mobile, you've got slowness and the added annoyance of possibly higher battery drain. It's time to start thinking about web site performance as a feature in and of itself. Because if you're too slow, none of your other features will matter. Your visitor will be gone before the page renders.

Creating scalable web sites that can handle many simultaneous requests and still provide fast experience for each user is hard.

Sergey Chernyshev will compare these two directions of web engineering and describe the differences between them, he will also cover current performance trends and describe different approaches to take in order to measure and analyze Web Performance in comparison to traditional methods that are successfully used to test scalability of web systems.

The document discusses using service level objectives (SLOs) to provide a consistent user experience for services. It notes that establishing SLOs sets user expectations for acceptable performance and availability. The document advocates engineering systems to meet SLOs consistently rather than having occasional outstanding performance, and cites Google's Chubby service as an example. It acknowledges that SLOs need to be contextual and may change over time to meet evolving user needs and priorities around performance and availability.
