Performance Testing with JMeter 3 - Third Edition

By: Bayo Erinle

Overview of this book

JMeter is a Java application designed to load and test performance for web application. JMeter extends to improve the functioning of various other static and dynamic resources. This book is a great starting point to learn about JMeter. It covers the new features introduced with JMeter 3 and enables you to dive deep into the new techniques needed for measuring your website performance. The book starts with the basics of performance testing and guides you through recording your first test scenario, before diving deeper into JMeter. You will also learn how to configure JMeter and browsers to help record test plans. Moving on, you will learn how to capture form submission in JMeter, dive into managing sessions with JMeter and see how to leverage some of the components provided by JMeter to handle web application HTTP sessions. You will also learn how JMeter can help monitor tests in real-time. Further, you will go in depth into distributed testing and see how to leverage the capabilities of JMeter to accomplish this. You will get acquainted with some tips and best practices with regard to performance testing. By the end of the book, you will have learned how to take full advantage of the real power behind Apache JMeter.

Remote testing with JMeter

JMeter has inbuilt support for distributed testing. This enables a single JMeter GUI instance, known as the master, to control a number of remote JMeter instances, known as slaves, and collect all the test results from them. The features offered by this approach are as follows:

  • Saving test samples to the local machine
  • Managing multiple instances of JMeterEngine (slave nodes) from a single machine
  • Replicating the test plan from the master node to each controlled server without the need to copy them to each server


JMeter does not distribute the load between servers. Each server will execute the same test plan in its entirety.

Though the test plan is replicated across each server, the data needed by the test plan, if any, is not. In cases where input data such as CSV data is needed to run the tests, such data needs to be made available on each server where the test plan will be executed. This can be a shared network mount that all the servers can get to.
