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 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.

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.

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

Hirsch Performance, MapTun Performance, Nordic Uhr, and BSR AB, all tuners specializing in Saab models, can increase this to a maximum of approximately ECE ( 220 kW ).

The Baldrige Criteria for Performance Excellence serve two main purposes: ( 1 ) to identify Baldrige Award recipients that will serve as role models for other organizations and ( 2 ) to help organizations assess their improvement efforts, diagnose their overall performance management system, and identify their strengths and opportunities for improvement.

* Performance libraries serve performing music groups, particularly large orchestras, by acquiring, preparing, and maintaining music for performance.

The album won a Grammy in 2000 ; as an indicator of how difficult it is to classify Waits's music, he was nominated simultaneously for Best Contemporary Folk Album ( which he won ) and Best Male Rock Vocal Performance ( for the song " Hold On "), both different from the genre for which he won his previous Grammy.

Cowell-Shah demonstrates by example )

Performance artists and theorists point to different traditions and histories, ranging from tribal to sporting and ritual or religious events.

Crenna portrayed the state senator James Slattery of California in the TV series Slattery's People ( 1965 – 66 ), and for his acting in this series, he was twice nominated for Emmy Awards with slightly different names: for " Outstanding Individual Achievements in Entertainment ", in 1965, and for " Outstanding Continued Performance by an Actor in a Leading Role in a Dramatic Series ", in 1965.
