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:
performing a sequence of input events by a computer; receiving information which updates a graphical user interface (GUI), wherein the GUI displays a sequence of frames rendered by a remote application, the GUI containing an object that is modified in response to the input events, wherein a color of the object is varied between successive frames in the sequence of frames; sampling colors at a number of pivot points on the GUI; determining a motion vector for the object on the GUI based on the color of the object between the successive frames obtained from the sampling; and matching the motion vector to a previously performed input event; and computing a display performance metric for the remote application based on the motion vector and the corresponding input events.
