This subrepository holds benchmarks used by the Go performance dashboard:
http://build.golang.org/perf

All benchmarks are compiled into a single binary, to build it execute:

	go install golang.org/x/benchmarks/bench

When you run the binary without any flags, it prints comma-separated list of
available benchmarks:

	./bench
	build,garbage,http,json

To run a benchmark execute:

	./bench -bench=json

The binary has a number of flags to control benchmark duration, etc.
Run 'bench -help' to get the full list of flags.

When the benchmarking finishes, the binary prints results:

	GOPERF-METRIC:allocated=7872994
	GOPERF-METRIC:allocs=105483
	GOPERF-METRIC:cputime=196757680
	GOPERF-METRIC:gc-pause-one=5762425
	GOPERF-METRIC:gc-pause-total=2650715
	GOPERF-METRIC:rss=63655936
	GOPERF-METRIC:sys-gc=3407366
	GOPERF-METRIC:sys-heap=53575680
	GOPERF-METRIC:sys-other=5253938
	GOPERF-METRIC:sys-stack=229376
	GOPERF-METRIC:sys-total=62466360
	GOPERF-METRIC:time=206958902
	GOPERF-FILE:cpuprof=/tmp/19.prof.txt
	GOPERF-FILE:memprof=/tmp/20.prof.txt

Description of metrics is available at:

A typical usage of the benchmarking binary from dashboard builder is:

	./builder -filelock=builderlock -build=false -bench -benchtime=5s \
		-benchnum=5 -benchmem=1024 -benchcpu=1,2,4,8,16 \
		-benchaffinity=85,85,85,21845 windows-amd64-perf
