The Apache JMeter™ application is open source software, a 100% pure Java application 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.
An open source load testing tool. Define user behaviour with Python code, and swarm your system with millions of simultaneous users. Tweet Follow @locustio. Stress Prime Orthos is a simple freeware to perform CPU stress test and RAM stress test. After the stress test is performed, you can view the information about errors and warnings, if encountered during the test. You can choose which stress test you want to perform, from the options: Small FFTs – stress CPU. WebLOAD is an open source load tester. I believe it was initially developed by the same guy that first developed Mercury LoadRunner. They also have a commercial version: WebLOAD Editions Comparison. If you're on a Windows platform and you have the Visual Studio Enterprise Edition you can use the Application Center Test tool as well. FurMark is a very intensive OpenGL benchmark that uses fur rendering algorithms to measure the performance of the graphics card. Fur rendering is especially adapted to overheat the GPU and that’s why FurMark is also a perfect stability and stress test tool (also called GPU burner) for the graphics card. Like Packet Sender, this tool could be more user friendly. And as with most open source and free network stress test software, it’s not suited to business needs. It’s available for Linux, Mac, and Windows and is simple to download and install. The source code is accessible from the download page.
What can I do with it?
Apache JMeter may 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.
Apache JMeter features include:
- Ability to load and performance test many different applications/server/protocol types:
- Web - HTTP, HTTPS (Java, NodeJS, PHP, ASP.NET, …)
- SOAP / REST Webservices
- FTP
- Database via JDBC
- LDAP
- Message-oriented middleware (MOM) via JMS
- Mail - SMTP(S), POP3(S) and IMAP(S)
- Native commands or shell scripts
- TCP
- Java Objects
- Full featured Test IDE that allows fast Test Plan recording (from Browsers or native applications), building and debugging.
- CLI mode (Command-line mode (previously called Non GUI) / headless mode) to load test from any Java compatible OS (Linux, Windows, Mac OSX, …)
- A complete and ready to present dynamic HTML report
- Easy correlation through ability to extract data from most popular response formats, HTML, JSON , XML or any textual format
- Complete portability and 100% Java purity.
- Full multi-threading framework allows concurrent sampling by many threads and simultaneous sampling of different functions by separate thread groups.
- Caching and offline analysis/replaying of test results.
- Highly Extensible core:
- Pluggable Samplers allow unlimited testing capabilities.
- Scriptable Samplers (JSR223-compatible languages like Groovy and BeanShell)
- Several load statistics may be chosen with pluggable timers.
- Data analysis and visualization plugins allow great extensibility as well as personalization.
- Functions can be used to provide dynamic input to a test or provide data manipulation.
- Easy Continuous Integration through 3rd party Open Source libraries for Maven, Gradle and Jenkins.
How do I do it?
- Using JMeter to understand how to use it
- Component reference to have detailed information for every Test element
- Functions reference to have detailed information and examples for every function
- Properties reference for all properties that allow you to customize JMeter

JMeter is not a browser
JMeter is not a browser, it works at protocol level.As far as web-services and remote services are concerned, JMeter looks like a browser (or rather, multiple browsers);however JMeter does not perform all the actions supported by browsers.In particular, JMeter does not execute the Javascript found in HTML pages.Nor does it render the HTML pages as a browser does(it's possible to view the response as HTML etc., but the timings are not included in any samples, and only one sample in one thread is ever displayed at a time).
