Usage: benchstat [flags] inputs...

benchstat computes statistical summaries and A/B comparisons of Go
benchmarks. It shows benchmark medians in a table with a row for each
benchmark and a column for each input file. If there is more than one
input file, it also shows A/B comparisons between the files. If a
difference is likely to be noise, it shows "~".

For details, see https://pkg.go.dev/golang.org/x/perf/cmd/benchstat.
