Serialization benchmark

Comparison of different serialization methods in Go.

Tested serialization methods:

• json
• xml
• gob
• yaml
• MessagePack
• Avro (hamba)
• Protobuf

Running

Run the following command to start the benchmark:

go run main.go

Benchmark results will be printed to the stdout.

Also, marshalled data will be saved in the output directory:

output/
├── avro.txt
├── gob.txt
├── json.txt
├── msgpack.txt
├── protobuf.txt
├── xml.txt
└── yaml.txt

Data

There is a synthetically generated user object to measure performance of serialization methods. You can find the definition of the structure in the sample package:

type User struct {
	Name    string
	Phone   string
	Balance float64

	BirthDay     *time.Time
	RegisteredAt time.Time

	ShoppingCart ShoppingCart

	Blocked bool
}

type ShoppingCart map[string]CartItem

type CartItem struct {
	Item     Item
	Quantity int32
}

type Item struct {
	ID        string
	CreatedAt time.Time
	Visible   bool
	OwnerID   int32

	Name        string
	Description *string
	Keywords    []string

	Price  float64
	Weight float32
}
