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. 

Share dashboards, basic auth and export HAR's

New features:

  1. Share your dashboard via a private url. Find the link on the "account" page.
  2. During site setup you can now add a user/pass for developments sites using basic authentication.
  3. On the individual test pages below the waterfall are links to the underlying WebPagetest waterfall and ability to export a HAR file.

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.   

Annotate your graphs

You can now annotate the main graph on SpeedCurve with notes about deployments or specific performance optimizations you may have put live. Just click on the "Annotate" link at the bottom right of the main graph to start adding them and comparing the before and after performance of your website. A vertical line will be placed on the graph where ever a note has been added.

Filter graphs by browser events

It's important to not obsess over the full load time of your website. The point at which a user can see content and interact with your site is arguably more important. To help keep a focus on this you can now filter the main graph by the different browser events like "start render" and "DOM complete".
