Engagement charts: See correlations between performance and user engagement

One of the best – and worst – things about real user monitoring is that it gives you unparalleled access to massive amounts of user data. The problem is when all this data leads to data indigestion. How do you know where to begin? And how do you know what to leave out in order to present a clear case for performance?

At SpeedCurve, we care about more than just showing you all your data. We want to show you the most important data. And we want to make it easy for you to share that data with people throughout your organization. That’s why we’re excited about the newest addition to our family of visualizations: engagement charts.

A/B Testing JSONP and the Preloader with RUM

SpeedCurve is a SPA (Single Page App) so we construct the charts dynamically using JSONP. It works great, but we're always looking for ways to make the dashboards faster. One downside to making requests dynamically is that the browser preloader isn't used. This isn't a factor for later SPA requests, but on the first page view the preloader might still bring some benefits. Or maybe not. We weren't sure, so we ran an A/B test. Long story short, doing the first JSONP request via markup caused charts to render 300 milliseconds faster.

SpeedCurve RUM: LUX

We're excited to announce SpeedCurve's RUM product, LUX.

The name LUX is a play on "Live User eXperience" and reflects how we've taken a different approach compared to other Real User Monitoring products. SpeedCurve's mission is to help designers and developers create joyous, fast user experiences. To do that, we focus on metrics that do a better job of revealing what the user's experience is really like. 

In addition to standard RUM metrics like page load time and total size, LUX includes innovative new metrics that have more to do with the user experience like start render time, number of critical blocking resources, images above the fold, and viewport size. LUX's RUM metrics help you figure out which design and development improvements will make your users happier and your business more successful.
