Benchmark encoding throughput

To measure encoding throughput, we set the number of bytes processed per single operation. In the code below, that will be the length of the message. As we can see in the result, JSON encoding processes approximately 281.23 MB/s and binary encoding approximately 1555.57 MB/s. This means based on the benchmark binary encoding can process more data per second.

func BenchmarkEncodeJSON(b *testing.B) {
	b.ReportAllocs()
	b.SetBytes(int64(len(benchmarkEvent.Message)))

	for b.Loop() {
		if _, err := EncodeJSON(benchmarkEvent); err != nil {
			b.Fatal(err)
		}
	}
}

func BenchmarkEncodeBinary(b *testing.B) {
	b.ReportAllocs()
	b.SetBytes(int64(len(benchmarkEvent.Message)))

	for b.Loop() {
		_ = EncodeBinary(benchmarkEvent)
	}
}

In the result below, we can see that binary encoding uses less allocation resources. Binary encoding uses less bytes and less number of allocation per event.
