JMeter an open source software is used to do load and performance testing and analyze the overall performance of dynamic web applications. 1000 concurrent threads do not mean 1000 concurrent users as real-life users don't hammer application as fast as they can, there are delays between requests called "think times". In this article we’re going to execute a test with 200 users ramping 1 user each 2 sec and let’s see what is the max user concurrency we can get. Concurrency is often used to define workload for load testing, as in concurrent users. If you have to test the web application, you may want to know how many concurrent users can a web handle. Several computers were used to run JMeter in an interface-less mode which helped running more concurrent threads. Scenario for 1000 Concurrent Users Per Minute (Jmeter) - Duration: 5:38. noThreads: number of concurrent users to execute, rampUp: duration (in seconds) between test start and peak load, lCount: total iterations count to run during the test. JMeter is an Apache open-source, it’s pure Java and can be used for load test and measure performance. what is the concurrent users in load testing using Jmeter.
