IE11 and average speed update
To keep inline with browser trends and average connection speeds SpeedCurve will begin updating the test setting every quarter.
For Q2 2014 we're switching to IE11 which is now the most popular version of IE according to Akamai and StatsCounter and the average connection speed has been updated to 9.8Mbps download, 2.5Mbps upload with a 10ms latency. The 9.8Mbps download speed is based on the latest State of the Internet report from Akamai.
SpeedCurve wins Webstock BNZ Start-Up Alley
I'm stoked that SpeedCurve has been chosen as one of two winners in the 2014 Webstock Start-Up Alley. I'll be using the 10k prize money and two flights to the US to attend Velocity Conf in San Fran in June and New York in September.
Performance tips for building responsive sites
The following article was originally published in the 2013 Performance Calendar. There's 31 great articles to explore in the calendar including Steve Souders's browser wishlist and Tim Kadlec's take on what it takes to create a performance culture.

Responsive Web Design (RWD) is now a well established technique yet it’s adoption is still surprisingly low. Guy Podjarny’s recent research shows that only one in eight websites is responsive. Often when responsive sites are designed the approach is primarily from a visual design perspective and teams struggle with the complexity of changing design and navigation patterns let alone any performance concerns, which become secondary. This can lead to serving the same sized assets to all browser widths resulting in a responsive site that is visually scaled but not performance optimised. On average responsive sites at 320 pixels wide are only 8% small than at 1600 pixels wide. Unsurprisingly these performance concerns and a lack of established techniques have made some hesitate when considering RWD adoption.

New weekly emails
I've redesigned the weekly email reports to provide more trending information so you can compare week on week performance improvements. They're nice simple visualizations for forwarding around your whole team.

Speed Matters talk at Auckland Web Dev Nights
Here's the slides from my presentation at the Auckland Web Dev Nights meetup. It's an overview of why front-end performance matter, how to monitor it and the challenges faced when building for an increasingly mobile world.
Sort browser waterfalls
Sort the items in a browser waterfall by Time, Savings and Slowest. Time is the default showing how assets loaded in the browser. Savings places assets at the top that have the greatest optimization potential and Slowest shows you which are the slowest overall requests.
