benchfmt: new benchmark parsing package This adds a new package for parsing the Go benchmark format. In contrast with the storage/benchfmt package, which this deprecates, the new package is a complete implementation of the format including parsing file-level configuration, benchmark lines, and benchmark names. This is the beginning of a substantial redesign of the perf module, which will culminate in a new benchstat that's substantially more featureful and modular. These new packages can live next to the existing packages, so it's not necessary to introduce a v2 of this module. The benchfmt API is designed for streaming use and expects the calling package to transform the results into some other representation. One such representation is coming in a following CL. The reader API is also designed to process millions of records per second on a typical laptop. This may seem unnecessary, but we've seen data volumes like this in practice.

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 install golang.org/x/perf/storage/localperfdata@latest go install golang.org/x/perf/analysis/localperf@latest localperfdata -addr=:8081 -view_url_base=http://localhost:8080/search?q=upload: & localperf -addr=:8080 -storage=http://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.
The easiest way to install is to run go install golang.org/x/perf/cmd/...@latest. You can also manually git clone the repository and run go install golang.org/x/perf/cmd/....
This repository uses Gerrit for code changes. To learn how to submit changes to this repository, see https://golang.org/doc/contribute.html.
The main issue tracker for the perf repository is located at https://github.com/golang/go/issues. Prefix your issue with “x/perf:” in the subject line, so it is easy to find.
