Apache JMeter

Apache JMeter is a free, written in Java tool to perform load testing client / server applications, which is developed by the Apache Software Foundation.

JMeter allows using compiling a test plan to specify which parts of the application ( such as multi-threaded ) to be passed through in order to get concrete results on the response time behavior. These are presented in the easy- to-use interface of JMeter. By logic components, listener, samplers, timer and configuration items can be created in every detail customized test plans. JMeter can also be used as a proxy component for recording a series of test steps that can be used as a basis for test plans. A special feature is that requests sent using Sampler not be limited to HTTP and HTTPS, but can also be created for FTP, SOAP and JDBC.
