Methods For Measuring Performance
There are two main methods by which application performance is assessed for production applications. The first is measuring the resources used by the application. The second is measuring the End User Experience which in and of itself has two components. The first, is the volume of transactions that are going through the system during the response time measurements, and the second is response time of an application from the perspective of the end user.
These methods for measuring performance will ultimately help build a performance baseline, which consists of three high level categories.
- Transaction Performance / Response Times (EUE). This can be measured at some point in the server, by a robot or simulated user, or by desktop agents that show the response time as measured at the desktop from the time the "enter" key is pushed to the time data is returned.
- Transaction Volume – (metrics trending)
- Resource Consumption (Infrastructure)
Application performance management is related to end-user experience management and real user management in that measuring the experience of real users in the use of an application in production is considered by many to be the most valid method of assessing the performance of an application. Maximum productivity can be achieved more efficiently through event correlation, system automation and predictive analysis which is now all part of APM.

Famous quotes containing the words methods, measuring and/or performance:
“The methods by which a trade union can alone act, are necessarily destructive; its organization is necessarily tyrannical.”
—Henry George (1839–1897)
“As an example of just how useless these philosophers are for any practice in life there is Socrates himself, the one and only wise man, according to the Delphic Oracle. Whenever he tried to do anything in public he had to break off amid general laughter. While he was philosophizing about clouds and ideas, measuring a flea’s foot and marveling at a midge’s humming, he learned nothing about the affairs of ordinary life.”
—Desiderius Erasmus (c. 1466–1536)
“Kind are her answers,
But her performance keeps no day;
Breaks time, as dancers,
From their own music when they stray.”
—Thomas Campion (1567–1620)
