JMeter Performance Testing
Performance testing is more important now than ever!
Some studies have shown that users of mobile and/or web apps can detect differences in response times of 250 milliseconds or more. And that the “slower” the app, the less likely users are to keep using it. No one wants to put up with a slow performing, an unreliable site in cases of purchasing, online test taking, bill payment, or simply browsing for information. The internet puts real meaning to the old saying “easy come, easy go”. It is easier to lose users than gain them and performance is a key factor.

The thing about “performance” is that measuring it is not simple nor straightforward. The rapid rise in mobile smartphone features, functions, and usage combined with the nascent growth of the Internet of Things (IoT), has resulted in complex systems that impact performance in complicated ways. In some cases, sluggish response times may arise due to exposure to latencies that exist outside the bounds of the local applications. In other cases, it may simply be a result of large numbers of simultaneous users.
In the profession of software QA & Testing, performance testing is no longer a simple checkpoint before going live. It is a comprehensive and structured process to evaluate an application to ensure it can deliver a great user experience under complex, challenging, and dynamic conditions.
Apache JMeter: XBOSoft’s Preferred Tool for Structured Performance Testing
XBOSoft decided to standardize on JMeter testing because it is highly regarded, widely accepted, and supports all the functions required for structured performance testing. It has been around for almost 20 years, possesses a very active development community, and as it is written in Java, it is considered cross-platform. While JMeter by itself possesses useful functions, a large number of plugins are available to greatly extend the range and capabilities of JMeter, from test function to output reports. Additionally, JMeter can test against a variety of interfaces, including HTTP, REST APIs, and others.
There are many benefits offered by open source software besides a low price. Because there are many developers constantly refining open source software, issues with security and quality can surface quickly and be addressed quickly. Open source applications can also be tailored in flexible ways as required by the business, another benefit not easily enjoyed by those using proprietary solutions.
What are the Major Challenges in Using Apache JMeter?
Setting up JMeter performance testing into a usable configuration can be tricky. Because JMeter is not a native application per se, a Java environment must be configured prior to installing JMeter. Plugins need to also be downloaded and installed. And in order to handle large numbers of simultaneous Virtual Users (Vusers), JMeter will need to be configured in a primary/replica configuration.
Perhaps the main challenge with using JMeter is not getting it operationally running, but prioritizing what JMeter will test and be analyzing results data to determine actionable improvements. You can’t test everything. Prioritizing tests, through inputs from analytics for how the program is being used, customer complaints, sensitivity to the function under test (e.g., financial transactions), are critical parameters that require a high degree of expertise to set.

XBO has experience in addressing all the “big challenge” issues. Over the years we have worked through them to create JMeter services that can be configured locally on a client’s private servers, or across dozens of geographically distributed JMeter cloud-based installations simultaneously driving hundreds of thousands of Vusers, while using effective configurations to capture the “right” set up.
