Performance Optimizer Observation Platform, or POOP for short, is a command-line tool that compares the performance of multiple commands using Linux’s perf_event_open functionality with a colorful terminal user interface. It reports peak memory usage as well as five other hardware counters, thus giving users useful insights when doing performance testing. Although Poop is a new project, while Hyperfine is a mature project with more configuration options and polish, poop’s added data points may inspire the Hyperfine maintainers to increase their output. However, Poop is Linux-only and treats the first command as a reference.
