A Principled Technologies test report 4

Remote Desktop Services: User experience across different

client architectures

that their virtual desktop clients will be able to handle the computing needs of their workers not only today,

but into the future as well. While the typical virtual desktop user may not regularly play 720p or 1080p videos,

ensuring that clients can meet these more advanced needs will ensure that most user demands can be met

today while preparing for future computing needs.

To determine the performance of each client while each completed multiple tasks, we played the

Robotica video at 1080p while simultaneously running a print job. We opened a target PDF file, selected Print,

started the video, returned to the Print PDF screen, and clicked OK to ensure that the print job executed while

the video was running.

Finally, we configured a dual-socket server and gigabit LAN environment in such a way that it did not

interfere with client performance. To ensure further that our testing focused on client performance, we ran

only one virtual desktop for each test. For detailed server configuration information, see Appendix A. For

detailed client configuration information, see Appendix B. For our detailed test methodology, see Appendix C.

WHAT WE FOUND

Figure 2 lists the ratings we use to describe the audio, video, and overall quality of the workloads, and

the criteria we used to determine each rating.

Rating

Meaning

Best

Essentially flawless audio and video quality

Very good

Near-perfect quality, with some minor syncing or skipping issues

Adequate

Moderate syncing or skipping issues

Poor

Severe syncing or skipping issues; practically unwatchable

Figure 2: Ratings we used for our workload testing and their meanings.

In addition to rating the video and audio quality of the advanced multimedia workloads, we also

recorded the average FPS as we note earlier. An average FPS rate of around 30 FPS indicates the best video

quality, while anything less than 30 FPS indicates that the video performance likely suffered. Please note that

we were unable to record average FPS rates from the Wyse C90LEW because its embedded operating system

is incapable of running the Fraps program.

Figure 3 shows the video playback results for the clients at 720p. The HP EliteBook8440p and HP

Mini5102 played the video with perfect audio and video quality, while the Wyse C90LEW displayed video that

skipped occasionally with the audio skipping throughout.
