Running stress- or load-tests of asynchronous REST/HTTP services with JMeter is only the first step in performance improvement. If the applications have problems when load increases, you need to find where the issues are. You can spend a lot of time to examine the code base before – if ever – finding the cause of the performance problem. This blog post provides an introduction on how to record and examine telemetry performance measurements with Yourkit3 after running JMeter tests.

JMeter is open source software designed to load test functional behavior and measure performance. This video shows how with JMeter as an automated test harness, You can trigger a breakpoint in a Jersey / JTA / JPA / Hibernate / MySQL / Glassfish RESTful web service.

Debugging live performance and scalability issues with business sponsors watching over your shoulder isn’t fun! Load testing is an often forgotten and seemingly difficult task that many people shy away from but a basic level of load testing is often enough to give you confidence that you’ve satisfied expectations regarding performance and scalability.

In this blog post, David Tobey shares with us how he used the open source load testing tool JMeter for functional testing. JMeter allows him to automate part of the functional testing process, making it more reliable and less time-consuming.

Apache JMeter is open source Java desktop software designed to load test functional behavior and measure performance. It was originally designed for testing Web Applications but has since expanded to other test functions.
