Golang Benchmark Test

内部程序是CPU密集型计算，因此编写了 Benchmark 测试算子的性能，并且希望在此基础上，将 Benchmark 在各服务器上执行，验证服务器性能情况。

Benchmark 编译

go test -c -test.bench=".*" ./filter/

执行后将在本地生成 filter.test

Benchmark 运行

首先在目标服务器上将编译好的二进制文件拉取到本地。

./teleport.benchmark-v1 -test.bench=".*" -test.cpu=1 -test.count 5

Golang test 参数详解

Usage of ./filter.test:
  -test.bench regexp
    	run only benchmarks matching regexp
  -test.benchmem
    	print memory allocations for benchmarks
  -test.benchtime d
    	run each benchmark for duration d (default 1s)
  -test.blockprofile file
    	write a goroutine blocking profile to file
  -test.blockprofilerate rate
    	set blocking profile rate (see runtime.SetBlockProfileRate) (default 1)
  -test.count n
    	run tests and benchmarks n times (default 1)
  -test.coverprofile file
    	write a coverage profile to file
  -test.cpu list
    	comma-separated list of cpu counts to run each test with
  -test.cpuprofile file
    	write a cpu profile to file
  -test.failfast
    	do not start new tests after the first test failure
  -test.list regexp
    	list tests, examples, and benchmarks matching regexp then exit
  -test.memprofile file
    	write an allocation profile to file
  -test.memprofilerate rate
    	set memory allocation profiling rate (see runtime.MemProfileRate)
  -test.mutexprofile string
    	write a mutex contention profile to the named file after execution
  -test.mutexprofilefraction int
    	if >= 0, calls runtime.SetMutexProfileFraction() (default 1)
  -test.outputdir dir
    	write profiles to dir
  -test.parallel n
    	run at most n tests in parallel (default 40)
  -test.run regexp
    	run only tests and examples matching regexp
  -test.short
    	run smaller test suite to save time
  -test.testlogfile file
    	write test action log to file (for use only by cmd/go)
  -test.timeout d
    	panic test binary after duration d (default 0, timeout disabled)
  -test.trace file
    	write an execution trace to file
  -test.v
    	verbose: print additional output
