+## How to run Benchmark
+
+* Run this command for Atomic Example.
+
+`$go test -benchmem -run=^$ -bench ^BenchmarkAtomic$`
+
+* Run this command for Mutex Lock Example.
+
+`$go test -benchmem -run=^$ -bench ^BenchmarkMutexLock$`
+
+### Example Results
+
+* **Atomic**
+  * goos: darwin
+  * goarch: amd64
+  * pkg: raceConditionPointersFix
+  * cpu: Intel(R) Core(TM) i5-7360U CPU @ 2.30GHz
+  * BenchmarkAtomic-4 --- 4977807 --- 236.2 ns/op --- 24 B/op --- 1 allocs/op
+  * PASS
+  * ok raceConditionPointersFix 1.895s
+
+
+* **Mutex Lock**
+  * goos: darwin
+  * goarch: amd64
+  * pkg: raceConditionPointersFix
+  * cpu: Intel(R) Core(TM) i5-7360U CPU @ 2.30GHz
+  * BenchmarkMutexLock-4 --- 4626063 --- 260.3 ns/op --- 33 B/op          1 allocs/op
+  * PASS
