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 ...
A graphical demo running as a benchmark of the OGRE engine. In computing, a benchmark is the act of running a computer program, a set of programs, or other operations, in order to assess the relative performance of an object, normally by running a number of standard tests and trials against it. [1]
PSI analyzes these metrics to determine if a page meets the Core Web Vitals assessment criteria. These are also used as a SEO ranking signal. Lab Diagnostics. PSI uses Lighthouse to analyze a web page in a simulated environment. It provides scores and recommendations for various categories like Performance, Accessibility, Best Practices, and SEO.
ApacheBench (ab is the real program file name) is a single-threaded command line computer program used for benchmarking (measuring the performance of) HTTP web servers. [1] Originally it was used to test the Apache HTTP Server but it is generic enough to test any web server supporting HTTP/1.0 or HTTP/1.1 protocol versions.
In computing httperf (pronounced h-t-t-perf) is a testing tool to measure the performance of web servers. It was originally developed by David Mosberger and other staff at Hewlett-Packard Research Laboratories. [1] httperf can test HTTP pipelining workloads. [2]
Performance measures include elapsed time of the test, the amount of data transferred (including headers), the response time of the server, its transaction rate, its throughput, its concurrency and the number of times it returned OK. These measures are quantified and reported at the end of each run. [4] This is a sample of siege output:
