Application Performance Measurement

Description

OVERVIEW OF APPLICATION PERFORMANCE MEASUREMENT

          Application performances will always be affected by resource constraints. Your user may experience these constraint as application instability, but the underlying cause can be any of the metric that define application performance.It is therefore vitally important to describe performance as a ratio of some measurable quantity—response, throughput, availability, or requests.Indeed, it can be difficult to estimate a realistic user load or predict use case, especially if you are about to launch a new website or services. At the same time, you should at least know how your new service will be used once launched, and how traffic is expected to evolve over time.Not every end-user request makes it to our application environment. Many component impact load times, including connection speed, browser characteristic, latency, content-delivery network, and geographic location. There are cloud-based and offline testing services that can execute load from different data centers using different browsers and different global locations.
