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 →

RedLine13 Improvements help load test up to the "Red Line"

We’ve implemented a number of improvements, called Release 2018-06-22, to help make RedLine13 more useful to you. They include user interface improvements, bug fixes, better reliability and more. Below are a handful of those updates. New Features Sometimes, JMeter tests that ended abruptly or were cancelled would fail to generate the final JMeter report due to JMeter’s JTL file being truncated. We’ve added code to detect and correct that so you can see the report forRead 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 →

Increasing the transaction levels and user levels can require you to tune your load tests. That may take some detective work. Here’s a real example. The Problem. A RedLine13 customer had an API test that ran for 12 minutes and generated around 500 transactions a second when run locally on their PC. Taking the same test running on Redline with 4 separate machines they expected to generate 2000 transactions but they were generating around 1040 transactions.Read More →

When companies are growing fast, their main concern is not scaling. Until it’s an issue.  This is part of maturing devops (development operations). They need, or will need, load testing. Then the questions come up. This blog post should be seen as practical load testing advice, along with the right questions, for any company that is grappling with the need to load test. Load Testing 101 Load testing is based on user requirements. For example, loadRead More →

We sometimes get questions such as “Can I run my Load Test from multiple locations?” The answer is “yes, easily”. It makes sense that testing from one location is not the real world. Therefore, you want to test from multiple locations to simulate the real environment that your site gets, whether that is across your region or across the world. Configure to Run Your Load Test from Multiple Locations So when you configure your test, you simply chooseRead More →
