In a recent experiment, we noted that deploying a CDN shaved only 0.8 seconds from start render time for 3G users, raising the question: how effective are CDNs when it comes to mobile performance?
Americans spend an estimated 37 billion hours per year waiting in lines, so it’s not surprising there’s a large – and growing – field of research dedicated to studying the psychology of waiting. A recent trip down this research rabbit hole yielded some interesting insights about in-store versus online waiting.
As a former senior software engineer at Walmart Labs, Aaron Kulick has been in the enviable position of being able to pioneer what Walmart is doing with its big data strategy. He and Joshua talked about what it’s like working with bigger and bigger data sets, the long term utility of big data and whether or not there’s much room left for innovation and learning on the RUM journey.
I’ll come right to it: As of this week, I’m retiring. I’m leaving this blog and our technology in more than capable hands, and I’m very excited about the future direction of both.
Lori and I covered a lot of ground in our chat, from the early acceleration pioneers who helped birth modern-day FEO, to ADCs and SDNs and a bunch of other cool acronyms. Lori also made a heroic attempt to convince me that the cloud is interesting. You’ll have to listen to the podcast to see if she succeeded.
This slide deck gives an excellent overview of the business value of performance, mobile performance issues, measurement and tools, front-end problems and front-end optimization (FEO), the role of CDNs in performance, and some great case studies and examples.
If we truly care about delivering a top-tier online experience, we need to consider creating solid service level agreements for our sites, our third-party content, and our cloud providers.
In December 2011, the median load time for a site in the Alexa Retail 2000 was 5.94 seconds. Just twelve months later, the median was 7.25 seconds. At this rate of growth, this number could hit almost 9 seconds by the end of this year.
In this podcast, former Googler and SPDY creator Mike Belshe and I had a far-reaching discussion about time, SPDY, start-ups, mobile, native apps, and HTML5 versus Java. I enjoyed it immensely. I hope you do, too.
We studied the page speed and composition of 400 top European retailers to see how these sites would load for visitors using Chrome 23 (the most popular browser in the EU at the time of testing). While the results may not be shocking if you’ve been paying close attention to this space, they may come as an eye-opener to online retailers in the EU.
