Go performance measurement, storage, and analysis tools

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 benchmark result storage system.

analysis contains the 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
go get -u
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 get -u You can also manually git clone the repository to $GOPATH/src/
