After a stint as the poster child for web performance optimization, Shopzilla lost its way and saw its page load times slowly creep from an impressive sub-2 seconds up to more than 5 seconds. Lead architect Tim Morrow explains exactly what went wrong.
The mainstream web performance community is rapidly amassing reams of data in this area. But when it comes to the mobile web, we’re pretty much at square one. The problem is threefold: lack of performance-measuring tools, need for large-scale A/B testing, and lack of information sharing.
VIDEO: O’Reilly’s Mac Slocum interviewed me at Velocity, and we covered a few topics: mobile web performance, the difficulties of data gathering, site speed and SEO, and easy ways that every “mortal company” (aka a company that’s not Google, Microsoft or Amazon) can optimize their site.
A summary of what’s been added to this popular post about performance stats and business metrics.
A collection of my favorite performance graphs and charts from Velocity 2010. Taken all together, these provide a pretty nifty snapshot of the current state of web performance.
When Network World invited me to whiteboard the issues with web performance, I jumped at the chance. In this video, I illustrate the performance problems in the current web landscape — from server time and round trips to browser differentiation and user expectations.
Here’s the slide deck from my Velocity presentation earlier today, where I presented case studies showing the relationship between site speed and business metrics.
Would you consider participating in an open project wherein contributors shared their performance and metrics data in order to gather and analyze realtime data from real websites? Would your organization? Is such a project even worthwhile?
Optimizing web performance may not be a red-button topic yet… but it will be. In the inaugural post for Web Performance Today, I talk about how internet speed has changed between 1999 and now and why, if you’re an ecommerce retailer — or anyone who cares about online conversion — you need to care about web acceleration.
