cmdperf – interactive command performance benchmarking

cmdperf is a terminal tool designed for developers who need to quickly measure, compare, and understand the performance characteristics of shell commands.

Whether you’re evaluating different implementations of a task (e.g., grep vs rg), checking the impact of command-line flags, or getting a feel for command latency under specific conditions (like concurrency or rate limits), cmdperf provides interactive feedback and clear, comparable results right in your terminal.

This is free and open source software.

Features include:

• Benchmark shell commands.
• Support for parallel execution.
• Compare commands.
• Real-time terminal UI with live statistics, progress tracking and ETA.
• Responsive.
• Color schemes.
