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
	BenchmarkGarbage/benchmem-MB=64-4     2000	   6443223 ns/op	   6008832 GC-bytes-from-system	    230521 STW-ns/GC	     15329 STW-ns/op	   2780501 allocated-bytes/op	     68636 allocs/op	 119041368 bytes-from-system	 104202240 heap-bytes-from-system	   8109400 other-bytes-from-system	 112427008 peak-RSS-bytes	 121511936 peak-VM-bytes	    720896 stack-bytes-from-system	  25194000 user+sys-ns/op

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.
