WPA offers a convenient one-liner installation for PowerShell or Git Bash on Windows. This script automatically downloads the latest release, registers WPA with detected MCP clients, and installs the .NET 8 runtime if it's missing, requiring no manual build steps.

Question 2

What types of performance issues can WPA help diagnose?

Accepted Answer

WPA can diagnose a wide range of performance problems, including slow application startup, high CPU consumption, excessive thread waiting, disk-bound regressions, AV-induced stalls, and issues related to process creation or image loading in Windows environments.

Question 3

What is WPA and what does it do?

Accepted Answer

WPA (Windows Performance Analyzer) is a C# MCP server that exposes over 17 Windows ETW (Event Tracing for Windows) trace analyzers. It's designed for in-depth performance debugging of Windows applications, covering aspects like CPU usage, wait times, file/disk/mmap I/O, and image loads.

Question 4

What are the core features of WPA for trace analysis?

Accepted Answer

Key features include 'top' views to quickly identify performance bottlenecks, corresponding 'caller-callee' drill-downs for detailed stack analysis, robust symbol resolution and caching for accurate function identification, and support for various trace types like CPU, wait, and I/O.

Question 5

How does WPA integrate with AI agents and other clients?

Accepted Answer

WPA integrates seamlessly with MCP-compatible AI agents like Claude Code, Claude Desktop, Codex, and Cursor via stdio JSON-RPC. This allows users to interact with WPA's analysis tools using natural language queries, streamlining performance investigations.
