Stop flushing your performance down the drain.
This command line tool uses Linux's perf_event_open functionality to compare the performance of multiple commands
with a colorful terminal user interface.
Usage: poop [options] <command1> ... <commandN>
Compares the performance of the provided commands.
Options:
--duration <ms> (default: 5000) how long to repeatedly sample each command
Tested with Zig 0.11.0-dev.3883+7166407d8.

Poop (so far) is brand new, whereas Hyperfine is a mature project with more configuration options and generally more polish.
However, poop does report peak memory usage as well as 5 other hardware counters, which I personally find useful when doing performance testing. Hey, maybe it will inspire the Hyperfine maintainers to add the extra data points!
Poop does not run the commands in a shell. This has the upside of not including shell spawning noise in the data points collected, and the downside of not supporting strings inside the commands.
Poop treats the first command as a reference and the subsequent ones relative to it, giving the user the choice of the meaning of the coloring of the deltas. Hyperfine always prints the wall-clock-fastest command first.
While Hyperfine is cross-platform, Poop is Linux-only.
