- 11. TESTING DENSITY • Testwith real workloads and users • Best way to assess experience (smoothness, responsiveness, colour accuracy) • Use GPU Profiling to assess correct GPU and Profile (e.g. GPU Profiler) • Avoid GPU Benchmarking tools (e.g. Unigine, Furmark, Games) • Designed to test a WHOLE GPU, not a shared system • Disable FRL and Vsync as a last resort • Be careful with artificial VDI server load testing applications (e.g. Login VSI) • Tests experience in the DC, not at the endpoint • Not designed for graphical workloads • Have some validity as a background server load Key Considerations http://images.nvidia.com/content/pdf/grid/guides/vgpu-profile-sizing-guidance-for-windows-10.pdf https://www.linkedin.com/pulse/creating-clarity-through-multiple-lenses-david-pfahler/
