Standard Deviation is an important metric in performance testing analysis and informs us how stable the application under test is. In other words, it tells us if the requests that occur during the test are consistent or not. Standard Deviation measures how the response times are spread out around the average response time (mean). A small standard deviation means that the response time of all the requests are close to each other.

Anything less is grounds for disappointment and even lost business. Facebook’s mobile device testing lab at the Prineville Data Centre is equipped with Android and iOS devices that test Facebook applications and Instagram.

Load testing is a type of performance testing that simulates a real-world load on any software, application, or website. Without it, your application could fail miserably in real-world conditions. That’s why we build tools like Retrace to help you monitor application performance and fix bugs before your code ever gets to production.
