Democratizing Windows Performance Analysis

Why is that app so slow!?

What is the system even doing!?

What code / component is responsible!?

Easily analyze the behavior and resource usage of Microsoft Office, Windows, and related apps:

• CPU
• Network Connections and Activity
• Memory: RAM, Heap, Virtual Memory
• File & Disk I/O
• Handles: Kernel, User, GDI
• Registry
• Thread Activity
• Anything and everything else!

What types of code does it work with?

• Native Code: C++ / C / Assembly
• Managed Code: C# / Common Language Runtime
• JavaScript: Chromium / Chakra

How does it do it?

• Uses Event Tracing for Windows (ETW) and Microsoft's Windows Performance Analyzer (WPA)
• Pre-configured to expose usage of common resources over time.
• Reveals the names of the modules and functions responsible (symbolic call stacks).
• Handles all the tricky cases with a few simple commands.
• Highly Customizable: 1000s of resource types are traceable.
• Straightforward Documentation gets you up-to-speed.

Programmers' Creed

I will claim credit for the functionality provided by my code.
I will accept responsibility for the resources it consumes.
