Performance testing is a subset of performance engineering, an emerging computer science practice which strives to build performance into the implementation, design and architecture of a system.

Performance testing can serve different purposes.

Performance testing is frequently used as part of the process of performance profile tuning.

Performance testing can be performed across the web, and even done in different parts of the country, since it is known that the response times of the internet itself vary regionally.

Performance testing technology employs one or more PCs or Unix servers to act as injectors – each emulating the presence of numbers of users and each running an automated sequence of interactions ( recorded as a script, or as a series of scripts to emulate different types of user interaction ) with the host whose performance is being tested.

Performance testing can be combined with stress testing, in order to see what happens when an acceptable load is exceeded – does the system crash?

* Performance at two or more standard deviations on standardized testing in three or more of the following CNS domains — sufficient for a FAS, PFAS or static encephalopathy diagnosis using 4-Digit Diagnostic Code

* Performance at or below the 16th percentile on standardized testing in three or more of the following CNS domains — sufficient for an FAS diagnosis using CDC guidelines

* Performance at two or more standard deviations on standardized testing in three or more of the following CNS domains — sufficient for an FAS diagnosis using Canadian guidelines

Performance testing by Florida Solar Energy Center conclusively proved that the increase in temperature at the hottest part of the day was no more than about 5 degrees F. In fact, this study showed that radiant barrier had the potential to decrease the roof temperature once the sun went down because it was preventing the heat loss through the roof.

Performance data gained from testing models towed in a long water tank ( referred to in yacht design as Ship model basin ) can suggest optimal combinations of parameters.

Pratt graduated summa cum laude in Kinesiology at Toronto's York University and took at job there in the Human Performance Lab, testing professional athletes including the players of the Toronto Maple Leafs, the Winnipeg Jets and the San Jose Sharks.

Currently, the track is home to the Fast Track High Performance Driving School, which is owned by new track owner Andy Hillenburg, and is used extensively for NASCAR testing.

* HP Performance Center: Application performance testing management solutions

HP Performance Center software is the de-facto standard for enterprise-level performance testing.

Dr. Jürg P. Blum, defined the term environmental finance ( Dissertation: Corporate Environmental Responsibility and Corporate Economic Performance ..... 1994 at USIU ) as a fairly new field, " concerned mainly with finance and investment regarding the ecological environment.

The Young Artists Performance Academy provides provides a nurturing environment for gifted classical musicians aged nine to 19.

* Environmental Performance Index, a method of scaling the effects of human impact on the natural environment

Senior Performance Coach-Senior Performance coaches have completed a 1 year course with over 400 hours of learning and practicing in a performance environment.

TDA coaches were trained to deliver lessons to all players within a club environment and to manage that club programme ; and the Performance Coach Award The PCA was formerly a Level 3 of the licence scheme.

The beginning of this movement can be traced back to David Canter's work and the founding of the " Performance Research Unit " at the University of Strathclyde in Glasgow, Scotland, in 1966, which expanded traditional ergonomics to study broader issues relating to the environment and the extent to which human beings were " situated " within it ( cf situated cognition ).

Tiered storage is a data storage environment consisting of two or more kinds of storage delineated by differences in at least one of these four attributes: Price, Performance, Capacity and Function.

Performance of the route was exemplary in terms of operated mileage ( before traffic causes ) and, despite operating through Southall, an area renowned for its challenging traffic environment, reliability was extremely good-at April 2006, ECT Bus was in second position in TfL's league table for smaller operators.

* Clone ( database ), a complete and modified copy of a software database environment that's often used for development or testing purposes

In 1954, the 23 man crew of the Japanese fishing vessel Lucky Dragon was exposed to radioactive fallout from a hydrogen bomb test at Bikini Atoll, in 1969, an ecologically catastrophic oil spill from an offshore well in California's Santa Barbara Channel, Barry Commoner's protest against nuclear testing, Rachel Carson's book Silent Spring, Paul R. Ehrlich's The Population Bomb all added anxiety about the environment.

The mobile phone network operated by Manx Telecom has been used by O < sub > 2 </ sub > as an environment for developing and testing new products and services prior to wider rollout.

Starting in 2006, flight tests have been undertaken for testing the innovative balloon system in low-gravity environment.

The tests are carried out in the user ’ s own environment ( rather than labs ) helping further simulate real-life scenario testing.

Other disadvantages include having reduced control over the testing environment and the distractions and interruptions experienced by the participants ’ in their native environment.

West Nile virus can be sampled from the environment by the pooling of trapped mosquitoes via carbon dioxide-baited light traps and gravid traps, testing avian blood samples drawn from wild birds, dogs and sentinel monkeys, as well as testing brains of dead birds found by various animal control agencies and the public.

Such a test suite contains software tools that allow the testing environment to execute all the regression test cases automatically ; some projects even set up automated systems to automatically re-run all regression tests at specified intervals and report any failures ( which could imply a regression or an out-of-date test ).

The performance testing environment should not be clubbed with User acceptance testing ( UAT ) or development environment.

This is dangerous as if an UAT or Integration test or other tests are going on in the same environment, then the results obtained from the performance testing may not be reliable.

As a best practice it is always advisable to have a separate performance testing environment resembling the production environment as much as possible.

Having a thorough understanding of the entire test environment at the outset enables more efficient test design and planning and helps you identify testing challenges early in the project.

This regulatory environment led to a sharp growth in the EMC industry supplying specialist devices and equipment, analysis and design software, and testing and certification services.
