Session Objectives Review Microsoft guidance for Windows 8 Optimization Performance Testing Approach

Why Windows 8 for VDI? Touch Performance Modern Applications
User Experience

Microsoft Guidance

Professional or Enterprise?
“Remote Computers running Windows 8 Enterprise provide the best user experience and support all management features. Therefore, Windows 8 Enterprise is the only supported edition for use with Windows Server 2012 virtual desktop collections (VDI).” Source:

Memory Allocation Dynamic memory will handle fluctuating demands for memory within a specified range Recommended Minimum 1GB Maximum based on workload Small -> 1.5 to 2GB Medium -> 2GB to 3GB Large -> 2GB to 4GB (or more) Consider using Blade Servers for Extra Large workloads NOTE: If you require VDI groups with different maximum memory multiple client collections will be required.

Memory Usage Comparison
32-bit 64-bit

Disk Partitions Using the default install routine will create a 350MB System Reserved drive to store BitLocker data Prevent the creation of this partition during OS installation using MDT 2012 to build the image Utilize the “DoNotCreateExtraPartition=YES” rule to prevent the creation of the “System Reserved” partition. Or use Scripted DISKPART commands….

Number of Virtual Processors
Default – 2 Virtual Processor Medium Usage – 4 Virtual Processors Heavy Usage – 4+ Virtual Processors Note: Is you are using the Hyper-V hypervisor, fairshare will balance usage of processors to avoid one client consuming all available physical processor bandwidth

Requirements to Support RemoteFX
GPU must support DirectX 11 A list of certified GPU’s can be found on the Windows Server Catalog web site – link At present there are 6 NVIDIA cards certified for RemoteFX RDVH or RDSH processor must support SLAT (Second-Level Address Translation) Intel Processors identify this with the term Extended Page Tables (EPT) AMD Processors identify this with the term Nested Page Tables (NPT) VDI guest VMs must use the Windows 8 64-bit WDDM v1.20 driver to prevent rendering issues RDVH or RSDH role service must be enabled on the RemoteFX server to provide RemoteFX in client sessions/VMs

Enabling RemoteFX On the Hyper-V Server
Confirm that the WDDM v1.2 driver is selected in the GPU drop down Check the “Use this GPU with RemoteFX”

Options for GPU on server
Windows Server Management Marketing 5/12/2018 Options for GPU on server CPU-emulated DirectX 11 software GPU Provides 3-D capabilities to sessions and virtual machines at high scale Optimized for knowledge worker workloads such as Microsoft Office and web browsing Provides the highest scale for session host and VDI RemoteFX vGPU Provides a virtualized hardware-accelerated DirectX 11 GPU for VDI, optimized for: Best performance for 3-D graphics-intensive applications Best experience with full animations and transitions Best application compatibility, running as a console session in a virtual machine © 2012 Microsoft Corporation.

Windows ADK (Assessment and Deployment Kit)
Windows Performance Recorder monitors Windows client performance Command Line: XPERF Performance Scenarios Steady State Performance Tracking System Boot Tracing Fast Startup Shutdown Reboot Cycle Standby/Resume Hibernate/Resume Xperf for the layman (Blog Post) layman-performance-analysis-unchained-windows-assessment-toolkit- revealed.aspx

Windows ADK Windows Performance Analyzer allows for the review and analysis of the performance logs collected by the WPR

Windows Performance Toolkit
By leveraging the power of the ETW model, we can capture metrics previously unavailable outside of a debugger/instrumented code environment. With this level of granularity, we can capture metrics like…. All processes and threads in user mode and kernel mode Deferred procedure calls (DPCs) and interrupt service requests (ISRs) Scheduling Disk and file I/O Memory Network It also helps analyze what the customer experiences: Catch the problem as it happens Capture anywhere, decode anywhere Integration with symbols

So what does that all mean? Well… it means we can use a single tool to tackle many of the most common problems for customers: Troubleshooting application behavior – High CPU, Handles, Etc. Gathers both usermode and kernel events at the same time Benchmark disk performance (or lack there of) Get a deep view into the entire boot/shutdown lifecycle XPERF is incredibly powerful and can be leveraged for a wide range of issues customers and engineers face daily.

Event Tracing for Windows (ETW) infrastructure allows the capture of kernel and/or application events, and can be enabled/disabled at any time without any restarts required.

Ever wonder what the system was truly doing right before that performance hang or disconnect?
“Black Box” ETW tracing can enable you to obtain the last few seconds prior to your VDI / Physical system having problems Always running, with minimal (~4mb) memory overhead Xperf –on Diag –BufferSize 1024 –MaxBuffers MaxFile 250 –FileMode Circular
