miniperfstab

miniperfstab is a small Python script designed to simplify performance benchmarking of Python code. It allows users to define functions and then easily measure their execution time under varying conditions. The primary goal of miniperfstab is to provide a straightforward way to get a quick sense of how different code implementations or parameter settings affect performance, without requiring complex setup or extensive profiling tools.

The script works by taking a list of functions as input and optionally accepting arguments for these functions. It then executes each function a specified number of times, recording the duration of each execution. After running the benchmarks, miniperfstab presents the results in a clear, tabular format, typically showing the average execution time, minimum execution time, and standard deviation for each function. This makes it easy to compare the performance of different functions side-by-side.

miniperfstab is particularly useful for developers who want to perform micro-benchmarking during the development process. It can help identify performance bottlenecks early on or evaluate the effectiveness of optimizations. Its simplicity makes it accessible even to those who are not deeply familiar with performance analysis tools. The script is lightweight and has minimal dependencies, making it easy to integrate into existing projects or use as a standalone utility. It is not intended to replace comprehensive profiling tools like cProfile or line_profiler, but rather to serve as a quick and accessible tool for rapid performance assessments.
