We have been asked some questions on how JMeter scaling works. First a little background and then we’ll talk about how you can do it. If you are running JMeter locally and you need to simulate a larger number of concurrent users, there are limitations on the number of concurrent users you can run. It depends on the CPU and memory of the machine. And running a large test on a single machine can quickly hitRead More →
While Apache Jmeter is packed with features and is extremely powerful, this popular testing tool can be a little daunting at times for first-time user that want to optimize their test plans. In this article we are going to take a look at 8 useful tips for optimizing JMeter tests plans which in turn help you become a more efficient tester. Don’t run Production Load Tests in GUI Mode While it’s okay to run small testsRead More →
The JMeter Dashboard Reporting Filter has a neat ability to only show reports for selected metrics in the JMeter Dashboard Report. Read more in Apache JMeter. We have added support for this in the JMeter Report Plugin in Advanced JMeter settings in RedLine13. If you configure the filtering options for the JMeter report then your RedLine13 graphs will have all your normal responses. While the JMeter Dashboard Report available after test completion in the “Output Files”Read More →
A very common practice in JMeter is to make the number of threads per server configurable by passing in as a parameter to your thread group. We recently received a question from RedLine13 customer University of California about this. Sundar Thiru, Manager of Performance and Automation Testing, asked how to configure JMeter thread counts per test in RedLine13. You simply launch this in RedLine13 and use Advanced JMeter Options to pass in your settings at runtime.Read More →
RedLine13 was built for JMeter Cloud Load Testing. That gives you several advantages. This allows you to scale your JMeter tests to any size. It works with Apache JMeter and other open source platforms and plugins. And you can easily make testing part of your CI/CD environment with Jenkins and other platforms. Background Before the cloud, testing was very expensive to run. The costs associated with running and maintaining the hardware needed for performance tests wereRead More →
Currently, the most popular approach for API testing is to send a JSON payload file instead of using data with parameters. This post will show how to do JMeter Load Testing with a JSON payload. To perform sending the JSON payload we need a different configuration. First, we need to add HTTP Header Manager into our HTTP Request in order to set Content-Type as application/json. We then put the JSON payload into the Body Data sectionRead More →
This is a load testing Q&A we did with RedLine13 Customer ON24. ON24, Inc. is a San Francisco-based company that markets products and services based upon webcasting and virtual event and environment technology. ON24 is a privately held company whose primary venture capital investors are Goldman Sachs, Gold Hill Capital, U.S. Venture Partners, Canaan Partners and Rho Ventures. Christian Nguyen is the Load Test Engineer for ON24. Load Testing Q&A RedLine13: You just renewed your RedLine13Read More →
Disclaimer: This post is for those still using Beanshell. However, you should know that the Philippe Mouawad, JMeter contributor, has asked us to pass on that everyone should “avoid Beanshell in favor of JSR223 + Groovy because Beanshell is old, slow and does not support Java 5 and upper syntax.” If you still will be using Beanshell for whatever reason, here are Beanshell for JMeter Best Practices. JMeter has powerful abilities to perform general tasks outRead More →
Alexander Podelko, who talks and writes about performance-related topics, recently wrote in his latest load testing report that “It appears that Apache JMeter became the most popular load testing tool.” In this report he looked at the state of the load testing space since his previous report five years earlier. And he found that load testers use JMeter the most. Alexander continued: “Another interesting trend is that JMeter scripts become a de facto standard.” So weRead More →
I am a committer and member of the JMeter Project Management Committee at Apache. I work at SeLoger, the biggest French Real Estate platform. Performance matters at SeLoger and load testing is one of the ways we use to achieve good performance. In this post, I will talk about API Load Testing with cURL and RedLine13. SeLoger faces many challenges when performing load tests: Many websites Many sprint durations Small performance team But fortunately to achieveRead More →
