A Principled Technologies test report 3

Remote Desktop Services: User experience across different

client architectures

WHAT WE TESTED

About multimedia redirection

Multimedia redirection is a technology that lets physical clients use their local CPUs and graphics cards

to format and play media content. Without MMR, this processing demand is on the hosting server, thus

causing the server to utilize more resources per virtual desktop. For testing, we ran with MMR enabled on all

clients but the Wyse C90LEW, because it does not support MMR. For information about the benefits MMR

provides for virtual desktop deployments, including the reduction of server utilization, please see our

corresponding report at

About Remote Desktop Services

RDS is one of the core virtualization technologies available in Windows Server 2008 R2. According to

the Microsoft Web site, RDS represents the company’s progress toward providing the best virtualization

platform for accelerating and extending desktop and application deployments from the data center to any

device. In addition to the traditional session virtualization scenario (formerly known as “Terminal Services”),

Remote Desktop Services is expanding its role to provide an extensible platform for a Virtual Desktop

Infrastructure. For more information on RDS, see http://www.microsoft.com/windowsserver2008/en/us/rds-

How we tested Remote Desktop Services

To test the performance of the three clients running Remote Desktop Services, we used two video

workloads:

 Microsoft Robotica video, available for download at http://www.highdefforum.com/high-

definition-movies-video-clips/6537-official-hd-video-clip-list.html

 Robotica video while running a print job

We rated the video and audio quality of the video workloads on each client. We installed Beepa®

Fraps® on the clients to record the average frames per second (FPS) rate that each client achieved, and

assigned overall quality scores based on the quality of the video and audio on each client. Note that we were

unable to record average FPS rates for the Wyse C90LEW because its operating system was incapable of

running the Fraps program.

We chose advanced multimedia workloads at 720p and 1080p to measure the user experience

capabilities of the various client classes because a company looking to deploy a VDI solution needs to ensure
