Method and system for measuring display performance of a remote application

摘要

This disclosure describes a performance-monitoring system that computes a display performance metric of a remote application. During operation, the system performs a sequence of input events, and receives information which updates a graphical user interface (GUI). The GUI displays a sequence of frames rendered by a remote application in response to the input events. The system then samples colors at a number of pivot points on the GUI, and matches the a respective frame to a previously performed input event based on the sampled colors. The system subsequently computes a display performance metric for the remote application based on the frames and the corresponding input events.

1. A computer-implemented method, comprising:
determining an object in a graphical user interface (GUI) rendered by a remote server and displayed on a client device based on display information transmitted from the remote server to the client device over a network, wherein the object is manipulated by the server in response to one or more input events, wherein the object is a three dimensional object that is animated by the remote server; selecting a portion of the GUI displayed on the client device that includes at least some background around the object, wherein the portion of the GUI that includes at least some background of the object is selected based on dimensions of the object at various view angles; sampling colors of a set of points in the selected portion of GUI by the client device; determining whether the object has been updated by a frame update based at least in part on the sampled colors of the set of points in the selected portion of the GUI.
