Test recommendations
User experiences
Covers end-to-end scenario that typical users will experience
Examples: Boot, video playback, browser navigation, etc.
Windows Assessment Toolkit
Micro benchmarks
Specific operations within your application, service or driver that are critical to optimize for performance
Examples: Antivirus file scan, driver load, driver initialization routine, etc.
Event Tracing for Windows and Windows Performance Toolkit
Key performance metrics
Relevant data needed to assess and evaluate performance
Examples: CPU usage, disk IOs, memory usage, etc.

7. Event Tracing for Windows (ETW)
WinHEC 2015
8/9/2018 2:44 AM
Event Tracing for Windows (ETW)
What is it?
Fast, reliable, and versatile tracing framework
Dynamic trace control (no reboot or app restart required)
Uses an efficient non-blocking buffering and logging mechanism
Instrument code
Investigate performance issues pre/post shipping
Correlate app behavior with system resources usage
Accurately measure operations in your software for performance evaluation

Responsiveness
Unresponsiveness quickly generate customer dissatisfaction
3 key criteria to consider
User perception should determine performance goals
Measuring on the right hardware is critical (focus on low end systems)
Real-world performance, resource constraints and software preload must be taken into account
Holistic evaluation of resource utilization
Physical: CPU, GPU, disk, display resolution, memory, network, battery
Logical: critical sections, critical resources

9. Example: Fast Startup (a.k.a. Hybridboot)
WinHEC 2015
8/9/2018 2:44 AM
Example: Fast Startup (a.k.a. Hybridboot)
From a low power state to a responsive desktop
Boot, Fast Startup, Standby, Hibernate
Usually I/O and CPU intensive
Highly impacted by OEM app preload
Startup applications, services and logon scheduled tasks
Defined as entries under RUN key and Startup folders
Also include hardware-related processes (energy saver, control panels, tray icons, etc.)

10. Software preload guidance
WinHEC 2015
8/9/2018 2:44 AM
Software preload guidance
Don’t launch unnecessary memory resident processes
Use trigger start services and avoid having services running all the time unnecessarily
Delay start process if possible with the Task Scheduler
Optimize resource usage on app launch
Reduce CPU/disk contention and steady state memory usage
Avoid managed code in boot path
Leverage Automatic Maintenance
Perform periodic tasks like updates, scans, etc. and avoid user impact
Analysis focus
Memory footprint of processes impacting hiberfile size
Critical path analysis of logon and device initialization (bad drivers, security providers)
CPU and disk resource consumption during post-on/off
