+# Integration package
+The main goal is to have integration tests here.
+
+### Performance test
+Right now we have `performance_test.go` to measure number of processed TX per second.
+In order to run it:
+```
+$ cd integration
+$ go test -bench=. -benchmem
+```
+
+Result:
+```
+10000            402421 ns/op          177370 B/op         90 allocs/op
+PASS
+ok      github.com/CityOfZion/neo-go/integration        4.360s
+
+```
+
+Which means that in 4.360 seconds neo-go processes 10 000 transactions.
