benchstat, cmd/benchstat: group benchmark results Go 1.9 and up write "pkg", "goos", and "goarch" keys in benchmark output. benchstat now understands benchmark labels, and uses them to separate incomparable benchmark results. cmd/benchstat gains a command-line flag called "-split" to control this, defaulting to "pkg,goos,goarch".

This subrepository holds the source for various packages and tools related to performance measurement, storage, and analysis.
cmd/benchstat contains a command-line tool that computes and compares statistics about benchmarks.
cmd/benchsave contains a command-line tool for publishing benchmark results.
storage contains the https://perfdata.golang.org/ benchmark result storage system.
analysis contains the https://perf.golang.org/ benchmark result analysis system.
Both storage and analysis can be run locally; the following commands will run the complete stack on your machine with an in-memory datastore.
go get -u golang.org/x/perf/storage/localperfdata go get -u golang.org/x/perf/analysis/localperf localperfdata -addr=:8081 -view_url_base=http://localhost:8080/search?q=upload: & localperf -addr=:8080 -storage=localhost:8081
The storage system is designed to have a standardized API, and we encourage additional analysis tools to be written against the API. A client can be found in the storage package.
