Benchmarks of Go serialization methods

Gitter chat

This is a test suite for benchmarking various Go serialization methods.

Tested serialization methods

Running the benchmarks

go get -u -t
go test -bench='.*' ./

To update the table in the README:

./stats.sh

Recommendation

If performance, correctness and interoperability are the most important factors, gogoprotobuf is currently the best choice. It does require a pre-processing step (eg. via Go 1.4's "go generate" command).

But as always, make your own choice based on your requirements.

Data

The data being serialized is the following structure with randomly generated values:

type A struct {
    Name     string
    BirthDay time.Time
    Phone    string
    Siblings int
    Spouse   bool
    Money    float64
}

Results

2019-08-28 Results with Go 1.12.6 darwin/amd64 on a 2.8 GHz Intel Core i7 16GB

Issues

The benchmarks can also be run with validation enabled.

VALIDATE=1 go test -bench='.*' ./

Unfortunately, several of the serializers exhibit issues:

  1. (minor) BSON drops sub-microsecond precision from time.Time.
  2. (minor) Ugorji Binc Codec drops the timezone name (eg. "EST" -> "-0500") from time.Time.

All other fields are correct however.

Additionally, while not a correctness issue, FlatBuffers, ProtoBuffers, Cap'N'Proto and ikeapack do not support time types directly. In the benchmarks an int64 value is used to hold a UnixNano timestamp.
