PERFORMANCE TESTING

12

• Two identical servers run LoginVSI Knowledge Worker to create a realistic customer environment

• CPU Utilization of the hosts is around 60-80%

• Testers don’t know which session is GPU accelerated

• Testers do the same tasks on both systems

• Access Devices (Thin Client/Monitor/Mouse/Keyboard) are the same with a single screen and 1080p resolution

• Predefined scenarios plus freestyle at the end.

• Scenarios include (Browsing, YouTube, Creation of PowerPoint, Google Maps, WebGL)

CPU ONLY VS. NVIDIA GRIDGPU with NVENC provide an average positive increase to UX of 34%

Higher is

better

Testing ran on two identical systems, CPU system was loaded up to 60-80% utilization, the GPU system ran the same workload

User Experience Scale

1 Unacceptable, unusable -

fire someone in IT!

2 Barely useable, borderline,

but I’ll get tired of this

soon

3 Tolerable, I guess I can

make do

4 Pretty good for a virtual

desktop

5 Outstanding - as good (or

almost) as physical

CLICK TO PHOTONWhat it is and why it matters

• Click-to-Photon is more than network latency

• Click-to-Photon is a key metric that contributes to the overall user experience

• Click-to-Photon defines how interactive/snappy the solution is

• Click-to-Photon measures the overall latency from the user perspective

• Click-to-Photon measures the time of the mouse click till the action is visible to the user

• includes latency of the USB device process, rendering the frame, displaying the frame, etc.

• Click-to-Photon in remote environments (VDI, etc.) in addition includes

• encode latency, network latency and decode latency

WINDOWS 10 IS DIFFERENT Windows 10 is Microsoft’s most graphical operating system

• Windows is differs to Windows 10

• requires more CPU resources

• Leveraged the GPU more

• NVIDIA GRID vGPU

• Improves user experience (as Microsoft intended)

• Reduces Click-to-Photon latency(snappy user interaction)

• Predictable and consistent user experience

• reduces CPU cycles to allow higher user density
