Very Sleepy is a free open-source sampling CPU profiler for Windows with a wxWidgets-based GUI. It can attach to any running native Windows application without recompilation and displays results as a full call graph, supporting both Visual Studio (PDB) and MinGW (DWARF) symbols.
Use cases
- profile a slow Windows application to find CPU hotspots
- sample-profile a running process without recompiling it
- profile MinGW-compiled programs with DWARF symbols
- view profiling results as a call graph and export to CSV
- profile an existing process by its PID from the command line
- resolve symbols via the Microsoft Symbol Server
When to choose
- you need a simple, zero-setup CPU profiler for native Windows apps
- you profile C/C++ code built with Visual Studio or MinGW
- you want to attach to an already-running process without instrumentation
- you prefer a lightweight GUI profiler over heavy suites like VTune
When to avoid
- you need profiling on Linux or macOS - this is Windows-only
- you need GPU, memory, or I/O profiling rather than CPU sampling
- you need continuous integration profiling or advanced trace analysis
- you need a cross-platform profiler for managed languages like .NET or Java
