Go benchmark analysis tools

Go Reference

This subrepository holds tools and packages for analyzing Go benchmark results, such as the output of testing package benchmarks.

Tools

This subrepository contains command-line tools for analyzing benchmark result data.

cmd/benchstat computes statistical summaries and A/B comparisons of Go benchmarks.

cmd/benchsave publishes benchmark results to perf.golang.org.

To install all of these commands, run go install golang.org/x/perf/cmd/...@latest. You can also git clone https://go.googlesource.com/perf and run go install ./cmd/... in the checkout.

Packages

Underlying the above tools are several packages for working with benchmark data. These are designed to work together, but can also be used independently.

benchfmt reads and writes the Go benchmark format.

benchunit manipulates benchmark units and formats numbers in those units.

benchproc provides tools for filtering, grouping, and sorting benchmark results.

benchmath provides tools for computing statistics over distributions of benchmark measurements.

Deprecated packages

The following packages are deprecated and no longer supported:

storage contains a deprecated version of the https://perfdata.golang.org/ benchmark result storage system. These packages have moved to https://golang.org/x/build.

analysis contains a deprecated version of the https://perf.golang.org/ benchmark result analysis system. These packages have moved to https://golang.org/x/build.
