Exploring real user (RUM) data can be a hugely enlightening process. It uncovers things about your users and their behavior that you never might have suspected. That said, it's not uncommon to spend precious time peeling back the layers of the onion, only to find false positives or uncertainty in all that data.
At SpeedCurve, we believe a big part of our job is making your job easier. This was a major driver behind the Synthetic Compare dashboard we released last year, which so many of you given us great feedback on.
As you may have guessed, since then we've been hard at work coming up with the right way to explore and compare your RUM datasets using a similar design pattern. Today, we are thrilled to announce your new RUM Compare dashboard!
With your RUM Compare dashboard, you can easily generate side-by-side comparisons for any two cohorts of data. Some of the many reasons you might want to do this include:
Let's take a tour...
Being able to set a sample rate in your real user monitoring (RUM) tool allows you to monitor your pages while managing your spending. It's a great option if staying within a budget is important to you. With the ability to sample real user data, comes this question...
This frequently asked question doesn't have a simple answer. Refining your sample rate can be hit or miss if you aren’t careful. In a previous post, I discussed a few considerations when determining how much RUM data you really need to make informed decisions. If you sample too much, you may be collecting a lot of data you may never use. On the other hand, if you sample too little, you risk creating variability in your data that is hard to trust.
In this post, we are going to do a bit of research and let the data speak for itself. I took a look at the impact of sampling at various levels for three t-shirt sized companies (Small, Medium, Large) with the hope of providing some guidance for those of you considering sampling your RUM data.
In this post, I'll cover:
Shortly before the end of the year, we snuck in a couple of last-minute gifts for 2021. It was a great year for SpeedCurve with a lot of renewed focus on RUM. We couldn't think of a better way to finish out the year than to launch the new Live and Page Views dashboards. Let's take a look!
I confess, I’m not a statistician. While I pride myself on the 'A' I received in my college statistics class, admittedly it was on a pretty steep curve. That said, I’ve been looking at performance data for many years and have found myself on both sides of the debate about whether or not the practice of sampling performance data is inherently a good or bad idea.
When it comes to real user monitoring (RUM), I’m convinced that the marginal cost of collection, computation, storage, etc. is not always great enough to warrant a practice of collecting ALL THE THINGS by default.
Like any experiment, how you sample RUM data – as well as how much data to sample – depends on the answers you seek. While certainly not an exhaustive list, here are some questions you might ask when looking at implementing a sampled approach to real user monitoring...
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.
Over the last few years the web performance monitoring toolset has expanded dramatically with the introduction of many new services and products. There are two main types of web performance monitoring, uptime monitoring and real user monitoring. SpeedCurve focuses on a third which I like to call web performance benchmarking.
