10 Best Performance Testing Tools to Release High-Quality Software

The performance testing is an integral part of the quality assurance process. The performance testing tools play a critical role in ensuring that the performance of the released software meets the agreed Service Agreement Levels (SLAs). The performance is the key to offer a higher user satisfaction levels. Here is a list of top 10 best performance testing tools that can help you in releasing high-performance software.

List of best top 10 performance testing tools:

Apache JMeter
The Grinder
Tsung
WebLoad
BlazeMeter
NeoLoad
LoadRunner
Loadster
Silk Performer
LoadComplete

1. Apache JMeter

The Apache JMeter is open source software that was initially created to test web applications but it has now added other test functions. The software is written in Java and it can be used to test the performance on static as well as dynamic resources such as dynamic web applications. The tool is useful for simulating a heavy load on a server, a group of servers to review the performance of an application under varied load conditions.

2. The Grinder

The Grinder is a Java-based load testing framework that performs distributed test execution with the help of various load injection machines. The tool uses Jython for creating test scripts to test the applications. It is suitable for performing parallel text execution on multiple machines. It also manages client connections and cookies automatically. The tool uses TCP proxy to keep a record of all network related activities.

3. Tsung

Tsung is based on XML configuration and it can simulate up to 50,000 concurrent users per physical computer as compared to the traditional injection tools which can only simulate up to 1000 users. The tool eliminates the need for developers to write scripts. It allows distributing testing load across a cluster of client machines along with the provision of using several IP addresses on a single machine.

4. WebLoad

WebLoad allows a user to test the scalability and integrity of the web application under the defined load condition. The tool creates virtual clients that simulate real-world loads. The virtual clients emulate the user behavior by performing different actions on the application. The results of the tests are collected from the Load Machines and it can be viewed in real-time in a tabular or graphical format.

5. BlazeMeter

BlazeMeter helps to test the performance of web applications, phone applications, websites, and APIs. The tool offers an agile platform that is compatible with Apache JMeter, Selenium, and other similar open-source tools. The tool is useful to perform a continuous delivery process by providing integration with the development environment. It also provides a powerful reporting and analysis function.

6. NeoLoad

This tool analyzes the response time and the number of concurrent users a web application can handle. The tool simulates thousands of users to analyze the response time when the application has to handle a heavy load. It also provides a solution to optimize the design and the development of the application so that better performance can be achieved.

7. LoadRunner

LoadRunner is used to reproduce a real business process that the user will perform when the application is in production. The tool is used to imitate a real user behavior as a large number of user access the application simultaneously. It uses minimal hardware to review the workload handling capability of an application accurately. LoadRunner reports the end-user response times for business processes and transactions to compare them against the service-level agreements.

8. Loadster

Loadster is a cloud-hybrid solution that performs distributed load testing of web applications, web services, and static websites. The tool can record test scripts in a web browser and then it can be tweaked with a graphical script editor. The results of the test can be exported to an HTML report with graphs and tables. It also provides live dashboards to view the real-time performance of an application.

9. Silk Performer

Silk Performer is a useful tool to evaluate the real-time user experience with the help of performance tracking and transaction monitoring. The tool is designed to ensure a consistent user experience across multiple devices. It also offers diagnostics to identify performance issues. It also provides integration with APM tools to resolve performance issues like memory leaks, loitering objects, etc.

10. LoadComplete

LoadComplete is a simple tool as it does not require any advanced programming skills. The tool is suitable for both HTML websites as well as Rich Internet applications based on AJAX, ASP, .NET, Java, Flash, Flex, and Silverlight. The tool enables users to quickly create load tests with the help of record & playback and visual programming. Load complete allows users to generate load from on-premises computers, virtual machines, and cloud. The tool offers end-to-end visibility at both client and server side.

Summary

The performance testing tools help to eliminate any performance glitches and plan for the resources that would be required to ensure high performance. These top 10 performance testing tools ensure that the quality of the released software in terms of performance meets the expectations of the end-user.
