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.
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 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/....
