| | Performance testing - Wikipedia, the free encyclopedia |
 | | Performance testing is a subset of performance engineering, an emerging computer science practice which strives to build performance into the design and architecture of a system, prior to the onset of actual coding effort. | | | Except in real-time computing, performance testing is frequently not performed against a specification. | | | In software engineering, performance testing is testing that is performed to determine how fast some aspect of a system performs under a particular workload. |

| | Approaches to Performance Testing |
| | For example, for repeatability, benchmark testing is the best methodology. | | | It is always a good idea to run a series of baseline tests first to establish a known, controlled environment to compare your changes with later. | | | It is a good idea to run this test twice—once with a fairly moderate user load (but below capacity so that there is no execute queue) and once with a high user load (so that there is a positive execute queue). |

| | UsabilityNet: Performance testing methods |
| | Performance testing is a rigorous usability evaluation of a working system under realistic conditions to identify usability problems and to compare measures such as success rate, task time and user satisfaction with requirements. | | | It is important that the users, tasks and environment used for the test are representative of the intended context of use. | | | Major usability problems are identified that may not be revealed by less formal testing, including problems related to the specific skills and expectations of the users. |

| | Web Test Tools |
| | Originally designed for testing Web Applications but has since expanded to other test functions; may be used to test performance both on static and dynamic resources (files, Servlets, Perl scripts, Java Objects, Data Bases and Queries, FTP Servers and more). | | | Performs scheduled and selective probes of network services, servers, desktops, operating systems, routers, firewalls, etc. to uncover and report systems vulnerabilities that might be open to attack. | | | Allows developers to test down to the unit level by simulating the internal software interfaces (message queues, mailboxes, etc.) Tool can learn what request/response scenarios are being tested for future tests and can work with any protocol, any message definitions, and any network. |

| | For example, this form of performance testing ensures that when one computer of a cluster fails or is taken offline, other machines in the cluster are able to quickly and reliably take over the work being performed by the downed machine. | | | This textbook fills the void between engineering practice and the academic domain's treatments of computer systems performance evaluation and assessment by providing a single source on how to perform computer systems engineering tradeoff analysis which allows managers to realize cost effective yet optimal computer systems tuned to a specific application. | | | Performs process to size all proposed new systems to determine the computer and network resources required, to determine hardware utilization, performance service levels and cost implications |
