While many facets of software testing can be done manually, performance testing is not one of them. It is highly dependent on testing tools, both to perform the actual tests and to help analyze and chart the results. Because of that fact, finding the right tool for the job is crucial. Different tools are better in different environments and codebases, and of course different budgets. Below is a list of the tools most often used by QA Mentor’s performance testing specialists.

A complex tool, it has proven capability and the current toolset is capable of performing a heavy load test and analysis for the scripted HTTP and HTTPS. The testing is executed by using the recordings and simple scripts. To carry out the test successfully, results and other statistics are taken through various test runs. This data can be later exported as reports. This is a free testing tool and it is distributed under GNU by Cyrano, which was later taken over by Quotium.
Loadstorm is a cloud testing tool for web applications. With Loadstorm, you have the option of creating your own test plans, testing criteria, and testing scenarios. You can generate up to 50,000 concurrent users in the cloud infrastructure, which enables you to send a large amount of requests per second. There are thousands of servers available around the world for this software, and there is no need of any scripting knowledge to use it. Loadstorm provides many graphs and reports that measure the performance in various metrics such as error rates, average response time and number of users. This tool is available for free, but the premium account comes with added features.
Httperf is a high performance testing tool for measuring and analyzing the performance of any web services and web applications. This is mainly used to the test the HTTP servers and its performance. The main objective of this testing tool would be to count the number of responses generated from this particular server. This generates the HTTP GET requests from the server which helps in summarizing the overall performance of the server. Through this tool, you will be able to conclude the rate at which the response is sent from each server and thereby the efficiency can be calculated. The ability to sustain the server overload, support the HTTP/1.1 protocol and compatibility with new workload are the three key features of this performance testing tool. This was originally developed by David Mosberger and many others at HP.
OctoPerf is a SaaS software aimed to improve quality and performance of web and mobile applications. OctoPerf lets you create thousands of realistic virtual users in a few clicks.
