Top Performance Testing Tools
What happens when millions of users with their unique credentials try to login at a time?
How will you forecast and prevent performance outages?
The best way this situation can be handled is through – virtual user (VU). For all our tests, the VU behaves just the way a real user would.
For the creation of as many VUs, as you would require and simulate real-time conditions, performance testing tools are employed. Not only that, Performance testing also tests for the peak load usage, breakdown point, long-term usage, etc.
To enable all with limited resources fast and to obtain reliable results, tools are often used for this process. There are a variety of tools available in the market- licensed, free wares and open sourced.
Check out our list which covers top performance testing tools (both open-source as well as licensed).
Open Source Performance Testing Tools

Tsung is a distributed load testing tool which is available free of charge as an open source software product. It is protocol-independent and can be used to stress Jabber/XMPP, HTTP, SOAP, LDAP and PostgreSQL servers. The tool can simulate very large numbers of users per server, making it ideal for analyzing and testing the performance of large-scale applications, such as instant messaging solutions.
High performance and ease of use are the main features of this tool. Tsung can simulate up to 50,000 simultaneous users per physical computer, whereas traditional injection tools can usually only simulate up to 1,000 users. Based on XML configuration, Tsung removes the need for developers to write complex scripts. The tool handles tasks such as managing cookies automatically, so developers can focus on designing the scenarios not managing lines of code.
Originally known as IDX-Tsunami, Tsung was first developed in 2001 by a company called IdealX. Its current name stands for Tsunami Next Generation. Developed in the Erlang programming language, the tool is now an open source solution that is actively developed and supported by ProcessOne.

The Rational performance tester is an automated performance testing tool which can be used for a web application or a server-based application where there is a process of input and output is involved. This tool creates a demo of the original transaction process between the user and the web service. By the end of it, all the statistical information is gathered and they are analyzed to increase the efficiency. Any leakage in the website or the server can be identified and rectified immediately with the help of this tool. This tool can be the best option in building an effective and error free cloud computing service. This Rational Performance tester was developed by IBM (Rational software division). They have come up with many versions of this automated testing tool.
Rational Performance Tester System Requirement: Microsoft Windows and Linux AIX good enough for this performance testing tool.

Performance testing tool for websites and intranet applications: WAPT refers to the Web Application Performance tool. These are scales or analyzing tools for measuring the performance and output of any web application or web related interfaces. These tools help us to measure the performance of any web services, web applications or for any other web interfaces. With this tool, you have the advantage of testing the web application performance in the various different environment and different load conditions. WAPT provides detailed information about the virtual users and its output to its users during the load testing. This is considered to be the best cost-effective tool for analyzing the performance of the web services. The WAPT tools can tests the web application on its compatibility with the browser and operating system. It is also used for testing the compatibility with the windows application in certain cases.
WAPT System Requirement: Windows OS is required for this testing tool
