Blog Listing: Testing

We recently improved our Edge Side Include (ESI) debugger UI and released a new API so developers can run a script to check whether their ESI code is running successfully at the edge.

You can locally test the effect of blocking or deferring third-party scripts and take action based on your results.

Akamai Test Center, a unique new testing tool that can help increase your confidence in the safety of configuration updates on your web properties, is now available.

In the ever-changing world of web performance analytics and measurements, this is one of the most common questions we hear: “How is mPulse different from Google Analytics?”

Most people in the performance engineering field agree that our skillset is derived from an intersection of disciplines that include testing, optimization, and systems engineering. Because of the interdisciplinary requirements, these skills can be difficult to accumulate organically, but it's possible!

If you’re ever offered a chance to throw a million or so beacon’s worth of user data into a Google-developed machine-learning system, I highly recommend you say yes. That’s what we did when Google approached us a year ago about partnering with them on a pioneering research project. The results have been eye-opening. In this post, I’ll walk through a...

The sooner performance issues are found, the cheaper they are to correct. The most expensive time to find a performance defect is when the code is in production. That’s why companies are starting to move performance testing earlier, into development. JMeter is an open-source project designed to load-test functional behavior and measure performance. It has grown in popularity with development...

Performance tests try to reduce the risks of downtime or outages on multi-user systems by conducting experiments that use load to reveal limitations and errors in the system. Here's how to report your test results for optimal impact.

In the world of performance testing, a lot has changed in the past 25 years. Today’s testing solutions have evolved light years beyond the tools that were developed back when Dallas was a city AND a TV show. That’s why we created this dictionary — to translate some of the circa-1989 client/server tool terminology to today’s web and mobile cloud-based...

I’ve worked in digital performance analytics for fifteen years. A recurring issue I run into is the misinterpretation of performance statistics. This misinterpretation has a couple of unfortunate outcomes: It leads customers to dismiss helpful suggestions and undervalue small performance changes. More specifically, it’s difficult to discern from the performance data that seemingly small improvements in page load time can...
