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
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
( and 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.
