Introduction
As performance testers, we are often asked to compare the difference in the performance between two versions of an application. Whatever the changes made in the second version (i.e., usage of new libraries, change of technological stack, etc.), ultimately, the business wants to know if the second version is better (or worst) and by how much.
This article discusses two solutions, including one based on a new JMeter plugin to help you "gauge" the improvement or degradation brought along by the second version of the application.
