Load testing (stress/performance testing) a web server can be performed using automation/analysis tools such as: Apache JMeter, an open-source Java load testing tool; ApacheBench (or ab), a command line program bundled with Apache HTTP Server; Siege, an open-source web-server load testing and benchmarking tool; Wrk, an open-source C load ...
Load testing is the simplest form of performance testing. A load test is usually conducted to understand the behavior of the system under a specific expected load. This load can be the expected concurrent number of users on the application performing a specific number of transactions within the set duration.
Specify an automated unit (component) performance test tool for the development/component unit test environment; this is used when no GUI yet exists to drive the components under development. Specify an automated tool for driving server-side unit (components) for the development/component unit test environment.
Load and performance testing is usually conducted in a test environment identical to the production environment before the software system is permitted to go live. Objectives of load testing: - To ensure that the system meets performance benchmarks; - To determine the breaking point of the system; - To test the way the product reacts to load ...
Web performance optimization (WPO), or website optimization is the field of knowledge about increasing web performance. Faster website download speeds have been shown to increase visitor retention and loyalty [ 1 ] [ 2 ] and user satisfaction, especially for users with slow internet connections and those on mobile devices .

PageSpeed Insights (PSI) is a free tool from Google that analyzes the performance of a web page on both mobile and desktop devices. It provides suggestions on how to improve the page's speed and overall user experience. Data and Metrics. PSI utilizes two main types of data:
Load testing tools analyze the entire OSI protocol stack whereas most regression testing tools focus on GUI performance. For example, a regression testing tool will record and playback a mouse click on a button on a web browser, but a load testing tool will send out hypertext the web browser sends after the user clicks the button.
Load testing tool WebLOAD combines performance, scalability, and integrity as a single process for the verification of web and mobile applications. [ 1 ] [ 2 ] [ 3 ] It can simulate hundreds of thousands of concurrent users making it possible to test large loads and report bottlenecks, constraints, and weak points within an application.
