Luke Stackwalker

Introduction

A screenshot of Luke Stackwalker displaying profiling results.

Luke Stackwalker is a C/C++ code profiler that runs on Windows. It uses call stack sampling to collect profile data, so no code instrumentation is required.
Luke Stackwalker can sample the call stack at an user-specified depth to not only provide a display of which functions in the program under test consume most CPU time, but it can also display a call graph showing how the program got there.

Feature list

Per-function CPU time cost view
Syntax-colored source code display showing stack samples per source line
Call graph display showing the call graph to a user-selected function in the function cost display
Supports multithreaded apps:

Stack is sampled on all threads of the target program.
Sample data can be viewed for a single thread or multiple selected threads simultaneously

Uses Microsoft symbol servers to load debug information for system DLLs
Profiling project settings can be saved and loaded
Profile data can be saved and loaded
Supports profiling both 32 and 64 bit applications

For more information, see the user's manual.

Current limitations:

Call graph collection works best for non-optimzed builds
Does not support binaries generated with GCC
