Behind the scenes of a Web slowdown: What Nouvola DiveCloud reveals

Posted by on September 29, 2015 11:54pm

From the user perspective, website crashes (and page slowdowns for that matter) are pretty simple. A user doesn’t care why the page crashed: She just wants to get what she needs. And so, in a matter of seconds she may be off the poorly performing site and looking elsewhere.

But from the perspective of the business that’s hosting an app, a slowdown or other performance problem can be staggeringly complex. Without a complete understanding of what went wrong, at what point the app became unable to bear the traffic, the business runs the risk of making the same mistake again and again.

When Nouvola tests web performance, we provide a lot more than a pass/fail score. We dive deep, and provide end-to-end performance measurements to give engineers and developers complete visibility so they can pinpoint problem areas.

These end-to-end user metrics or Key Performance Indicators (KPIs) will be the subject of a forthcoming paper that will detail all the ways Nouvola DiveCloud helps businesses test performance and parse the results.

Here’s a sneak peak:


At Nouvola, we understand that generating accurate results starts with creating realistic scenarios.

Setting up complex and nuanced test scenarios makes it possible to get all sorts of insights. We can look at overall performance across the entire collection of users, or we can drill down into different sessions or different user segments. For each session, we can also look at the individual HTTP request.

The results Nouvola DiveCloud provides useful metrics on throughput, response times and error rates. Some of the performance metrics we generate are plotted against the highest acceptable response time.

In addition to providing a visual snapshot of performance metrics, Nouvola DiveCloud also provides a summary of all the metrics contributing to the total response time.

All the metrics we produce are extracted from our raw data set that can be downloaded for further analysis. We know that the data holds the answers and we’re committed to arming our customers with all the data that can help them improve performance. Stay tuned for the detailed white paper on this topic.
