cmdperf 命令

命令示例

说明

cmdperf runs one or more shell commands repeatedly and gathers timing statistics, displaying them in a live terminal UI with a progress bar, ETA, and key metrics including mean execution time, standard deviation, and min/max ranges. It supports single command benchmarking, multi-command comparison, concurrent execution to simulate load, duration-based runs, and rate limiting for HTTP endpoint testing.
