19. Configuration Name Function
Configure Event log size/retention Set event log sizes to minimum size and configure retention to

(especially in pooled VM scenarios)
Disable Hard Disk timeouts,
increase disk I/O timeout, disable
NTFS last access timestamp,
disable System Restore, disable
hibernation, perform a disk
cleanup
Reduce I/O load when writes happen, allow longer writes, and
clean up disk before Sysprep process
Disable unneeded scheduled
tasks
36 scheduled tasks associated with disabled services or services
not useful in virtual environment
Reconfigure boot (quiet boot/no
animation), Disable UAC secure
desktop prompt, set visuals to a
minimum
Reduce overhead on vGPU and/or vCPU

21. Creates a VBScript that can then be run on the machine to configure the settings as defined.
The last release date was Aug of 2010, and there are no current plans to update to support Windows 8.

29. 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

30. 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.

31. 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.

33. Xperf –on Diag –BufferSize 1024 –MaxBuffers 1024 -MaxFile 250 –FileMode Circular
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

39. • How did the user log in?
• Console
• ICA
• PCoIP
• RDP
• What type of latency did the
user experience when starting
their session?
• Identify latency of an
application
• Identify latency with an
application calling a back-
end Server
• Identify application and
website focus
