Velocity 2010: Performance Impact, Part Two: More Findings from the Front Lines of Web Acceleration

4,088 views

Published on

Last year at Velocity, Strangeloop's VP Product, Hooman Beheshti, presented the findings from phase one of Strangeloop’s long-term research into the relationship between web performance and business benefits. The results were also published in Watching Websites. Since then, we’ve received a barrage of questions from the web performance community, which fueled phase two of our study. In this presentation, Strangeloop president Joshua Bixby offers our most recent findings.

Some of the community’s questions were:

* Who were the clients?
* How fast were the pages?
* What acceleration techniques were implemented?
* What happened to the key page components (such as JS size, payload and roundtrips) of the websites?
* How did changing key variables (page load time, payload, number of roundtrips, etc.) affect the outcome?

We’ve been collecting and analyzing data to help us answer these questions, as well as some new ones we’ve thought up along the way. Join us as we present our findings, and help us consider what areas deserve further study.
