Quantifying Perceived Performance of Virtualized Applications

Presented by

Ingmar Verheij, Senior Consultant, PepperByte

About this talk

Determining the user experience is challenging since the experience is based on many factors. The performance of an application is one of the factors that determine the user experience. The performance of an application can be influenced by many components. Delivering the application to a user usually involves a rather complex chain consisting of many (weak) links. For instance a (virtual) desktop system that has to compete for resources, a WAN connection that experiences delay and jitter or a backend infrastructure that has to deliver content. Although these are all different causes they have the same effect. The user doesn’t want to know what the cause is, although it can help to understand and maybe accept, they only perceive a decrease in performance. Quantifying and grading the performance of an application as perceived by a user is challenging and requires guidelines and thresholds. In this webcast Ingmar shares research about the psychological effect of (variable) response times on the user experience and existing methods of grading performance. He will also explain a process to quantify and rate the perceived performance of an application based on the response time of an application.
