Versions:
Very Sleepy is a lightweight, no-cost CPU profiler engineered for Windows developers working in C or C++, offering a straightforward way to identify performance bottlenecks at the function level. Designed by codersnotes.com, the tool attaches to running native processes, samples call stacks at a user-defined frequency, and then presents an interactive annotated disassembly and annotated source view that highlights hot paths and cumulative time spent in each routine. Its minimal footprint and non-intrusive sampling approach make it suitable for both interactive tuning during iterative development and for late-stage optimization before release, whether the project is a small console utility, a multi-threaded game engine, or a large-scale backend service. The single public build, version 0.91, imports Microsoft debug symbol formats automatically, supports collapsible call trees, and can export tabular reports for further analysis in spreadsheets or external visualization utilities. Because it requires no instrumentation recompilation, Very Sleepy fits naturally into existing Visual Studio or MinGW workflows, letting engineers compare profile snapshots across revisions, verify the impact of algorithmic changes, and ensure that performance regressions are caught well before continuous integration pipelines complete. The profiler is classified under Development & IT / Debugging & Profiling on get.nero.com, where the software is available for free; downloads are provided via trusted Windows package sources such as winget, always delivering the latest version, and the platform supports batch installation of multiple applications.
