PerfView is a free Windows-based performance-analysis tool for isolating CPU and memory performance issues, with special support for .NET applications and some ability to analyze Linux-collected data. It is built on the TraceEvent library, which collects and parses ETW and EventPipe traces.
Use cases
- profile cpu usage of a .net application
- diagnose memory leaks and heap issues
- analyze etw traces
- find performance bottlenecks in dotnet core apps
- collect and inspect eventpipe traces
- profile gc pauses and allocation issues
When to choose
- you need deep CPU or memory profiling on Windows, especially for .NET workloads
- you want a free, scriptable profiler backed by the TraceEvent library
- you need to analyze ETW or EventPipe trace files collected on Windows or Linux
When to avoid
- you need a cross-platform GUI profiler for non-Windows desktops
- you only need simple sampling without ETW trace analysis
- your target platform is macOS or Linux with no Windows machine available for analysis
