Apache JMeter is an open-source, pure Java application designed to load test functional behavior and measure performance. It was originally developed for testing Web Applications but has since expanded to other test functions. JMeter can be used to test performance both on static and dynamic resources, Web dynamic applications. It can be used to simulate a heavy load on a server, group of servers, network or object to test its strength or to analyze overall performance under different load types.

Simulate heavy loads on servers, networks, or objects to test strength and analyze performance under different load types.
Verify that your application does what it is supposed to do from a functional perspective.
JMeter can distribute load across multiple machines to simulate more realistic load scenarios.
Supports testing of web (HTTP/HTTPS), SOAP/REST Webservices, FTP, Database via JDBC, LDAP, JMS, Mail - SMTP(S), POP3(S) and IMAP(S), and more.
JMeter is highly extensible. Custom samplers, listeners, timers, functions, and more can be developed to meet specific testing needs.
Provides real-time graphical analysis of performance metrics.
A wide range of plugins are available to extend JMeter's capabilities.
Allows concurrent and simultaneous sampling of different functions by many threads.
Being a pure Java application, JMeter is highly portable and can run on any environment that has a compatible JVM.
Supports scripting with BeanShell and JSR223-compatible languages for more flexible test scenarios.
