JMeter Throughput Shaping Timer Results on RedLine13

Imagine you have a task to test the throughput of a system at a specified Requests Per Second (RPS) rate. To achieve the desired rate using regular thread groups you would need to play around with the number of threads and timers. This is not an efficient way to generate load. You can simply use JMeter’s Throughput Shaping Timer Plugin. The Throughput Shaping Timer plugin allows you to load test the RPS more effectively. It is designedRead More →


BeanShell is one of the most advanced JMeter built-in components. JMeter has rich built-in plugins which cover many needs of a performance test. For example, you might need some additional scripting while writing some complex tests. In such cases, it’s worth using Beanshell. In this post, we are going to be talking about testing complex logic with JMeter Beanshell and common use cases. Beanshell has the functionality to run java code and has access to JMeterRead More →


A while loop is a control flow statement that allows code to be executed repeatedly based on a given Boolean condition. It’s just a repeated IF→THEN statement. IF the condition is true, THEN execute the statements inside the IF block. JMeter implements this while loop by using the JMeter While Controller. The JMeter While Controller basically runs children Samplers and the controller continues to run until the condition becomes false in the condition field. The possibleRead More →

Rest APIs are increasingly popular these days.  They are also frequently being used in Microservices. In this guide, we are going to test REST APIs with authentication using JMeter.  We will see that HTTP Headers play a crucial role in access authentication. Introduction Let’s imagine you want to measure your Rest API request with JMeter and configure the request using JSON format and click the run button.  You will most likely receive an error from theRead More →

This document describes different types of JMeter thread groups and their usage. When talking about performance testing, a very important factor is to try to simulate the actual user behavior as best as possible. In JMeter, Virtual user groups are represented by Thread Groups. A Thread Group is a set of threads executing the same scenario. It is the base element for every JMeter test plan. There are multiple thread groups available which can be configuredRead More →

The purpose of the SyncTimer is to block threads until X number of threads have been blocked, and then they are all released at once. A SyncTimer can thus create large instant loads at various points of the test plan. Here’s how you can use JMeter SyncTimer for Load Testing. An Example – A Registration System Let’s say you’re load testing against a Racing Registration system. You have a JMeter script that pulls user information fromRead More →
