 # BeamNG SDK
 Simple SDK to interact with BeamNG.drive OutGauge data.
-There's some features missing listed in a comment in the
-`outgauge.go` file. I will implement them as necessary.
+
+## Development
+### Performance
+`go test -bench=BenchmarkReadData -benchmem -memprofile=mem.pprof`
+replace the function to be tested
+
+Use `go tool pprof` to analyze the results
+
+#### Results
+```bash
+# Previous footprint
+goos: linux
+goarch: amd64
+pkg: github.com/ESilva15/gobngsdk
+cpu: AMD Ryzen 7 5800X3D 8-Core Processor
+BenchmarkReadData-16    	 320931	     4058 ns/op	    100 B/op	      2 allocs/op
+PASS

+# Pretty good enough. I can finally go be productive instead of "procrastinating" here
