This subrepository holds macro-benchmarks used for Go performance
|
|
development and monitoring.
|
|
|
|
Each benchmark is compiled into a separate binary. To build and
|
|
install them all in the current directory, execute:
|
|
|
|
$ GOBIN=$PWD go get golang.org/x/benchmarks/...
|
|
|
|
To run a benchmark, simply execute its binary.
|
|
|
|
Each binary has a number of flags to control benchmark duration, etc.
|
|
Run with '-help' to get the full list of flags.
|
|
|
|
When the benchmarking finishes, the binary prints results in the
|
|
standard Go benchmark format [1]:
|
|
|
|
$ garbage

This format can be processed by tools like benchstat
|
|
(https://golang.org/x/perf/cmd/benchstat) and benchplot
|
|
(https://godoc.org/github.com/aclements/go-misc/benchplot).
|
|
|
|
Required extra tools:
|
|
For Linux, you need "perf". On Debian/Ubuntu, you can install
|
|
package "perf-tools-common" to get it. Run "perf" once with no
|
|
arguments to check if it requires additional packages to be installed.
