Virtual Desktops & Remote Workplaces Hyper-V

Relevant Remote End User Experience Factors Remoting protocol (Codec, protocol stack, streaming) Application type (GDI, DirectX, OpenGL, video, …) Host (server hardware & hypervisor, GPU support) Guest VM (Windows version, remoting components) Endpoint (client hardware & software, screen resolution) Network (TCP/UDP, bandwidth, latency, packet loss, VPN) Control plane (connection broker, gateway, …) In shared environments: other users (noisy neighbors)

Benchmarking Workflow Build Measure Analyze

Building a Remote Desktop Benchmarking Lab Endpoint Device Host Guest VM + Test Software Network WanEmu Record Archive Data Recorder Telemetry Secondary Users Primary User Firewall Lab Controller “REX Tracker” Control

Producing Synthetic User Workloads Primary Workload Sequences Secondary Workload Sequences 45-90 sec 60-90 min Start applications Start application Media Formats GDI Video Flash HTML5 DirectX OpenGL Personas Task Worker Info Worker Power User Office User Knowledge Worker Media Designer Start applications Save telemetry data Save telemetry data

Measuring Remote End User Experience (REX) Perceived user experience User interface response times - click to noticeable action and application start times Graphical output performance Screen refresh cycles - frame rates, flicker Supported graphics and media formats Dropouts, blurriness and artefacts - media quality Remote end user experience cannot be represented by a single score Solution: REX Analytics = screen videos + correlated telemetry data

Analyzing and Comparing Test Results
