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
poop is build using Zig-0.11. With Zig 0.11 installed,
building is as simple as running zig build in the root directory of the
repository. The resulting binary will be located in zig-out/bin/poop.
Most Linux distributions
still ship with Zig 0.10 or even Zig 0.9, so you may download the latest version of
Zig from the Zig website. Most likely you'll
need the linux-x86_64 xz tarball, that comes with a pre-built
zig binary. In order to install it, you can simply extract the tarball using
xz --decompress and add the resulting directory to your PATH environment.

Zig has a very fast release cycle, and development of poop is tightly coupled
to the development of Zig. Hence, it's possible that updating poop may require
updating Zig as well.
Tested with Zig 0.11.0-dev.3771+128fd7dd0 and
0.11.0-dev.3786+8dcb4a3dc.
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.
