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 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 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.

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

Performance status is often used as a measure to determine whether a patient can receive chemotherapy, or whether dose reduction is required.

Performance management can focus on the performance of an organization, a department, employee, or even the processes to build a product or service, as well as many other areas.

Performance management and improvement can be thought of as a cycle:

In Windows XP, it uses VMR7 by default, but can also be made to use the more advanced YUV mixing mode by enabling the " Use high quality mode " option in Advanced Performance settings.

A practical definition for OT can also be illustrated with the use of models such as the Occupational Performance Model ( Australia ), known as the OPM ( A ).

The various approaches to zoning can be divided into four broad categories: Euclidean, Performance, Incentive, and form-based.

In electrically powered heat pumps, the heat transferred can be three or four times larger than the electrical power consumed, giving the system a Coefficient of Performance ( COP ) of 3 or 4, as opposed to a COP of 1 of a conventional electrical resistance heater, in which all heat is produced from input electrical energy.

" Performance can only be inferred from wins, draws and losses.

The district is non accredited and did not achieve Accreditation With Distinction in Performance for the 2005-2006, 2006 – 2007, 2007 – 2008, and 2008-2009 school years, the highest honor a school in Missouri can receive.

Performance art can happen anywhere, in any venue or setting and for any length of time.

The in this time widely discussed difference, how concepts of visual arts and concepts of performing arts are utilized, can determine the meanings of a performance art presentation ( compare Performance: A Critical Introduction by Marvin Carlson, P. 103, 2-105, 1 ).

Performance art activity is not confined to European or American art traditions ; notable practitioners can be found in Asia and Latin America.

These " Ultra High Performance Liquid Chromatography " systems or RSLC / UHPLCs can work at up to 100 MPa ( 15, 000 lbf / in² ), or about 1000 atmospheres.

# Performance and power can be tuned in software to meet market needs.

Performance bottlenecks can be due to language limitations rather than algorithms or data structures used in the program.

Corporate culture can be found as a cause of injuries and be a reason for fining companies in US like in the case of U. S. Department of Labor's Mine Safety and Health Administration that fined of $ 10, 825, 368 Performance Coal Co. in April 2010, the largest fine in agency history, following its investigation of explosion at the Upper Big Branch-South Mine, operated by Performance Coal Co., a subsidiary of Massey Energy Co.

Performance improvement can occur at different levels:

* Performance improvement: well constructed PAs can be valuable tools for communication with employees as pertaining to how their job performance stands with organizational expectations.

* Performance can be improved by good human relations

) In large implementations, the planned value curve is commonly called a Performance Measurement Baseline ( PMB ) and may be arranged in control accounts, summary-level planning packages, planning packages and work packages.

According to Campbell's Model of The Determinants of Job Performance, job performance is a result of the interaction between declarative knowledge ( knowledge of facts or things ), procedural knowledge ( knowledge of what needs to be done and how to do it ), and motivation ( reflective of an employee's choices regarding whether to expend effort, the level of effort to expend, and whether to persist with the level of effort chosen ).

Performance ( rather than safety ) was also the reason for the rear-heavy design, because the canard could not be highly loaded ; anhedral wings were less affected by crosswinds and were consistent with the low yaw stability.

When The Battle of the River Plate was completed and screened for executives at the Rank Organisation, it went over so well that it was decided to hold the release of the film for a year, so that it could be chosen as part of the next year's Royal Film Performance ( in 1956 ), since 1955's film had already been selected.
