This is a test suite for benchmarking various Go serialization methods. To run:
go get github.com/ugorji/go-msgpack labix.org/v2/mgo/bson code.google.com/p/vitess/go/bson
go test -bench='.*' ./
No testing for serialization correctness is performed.
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
Tags map[string]string
Aliases []string
}
Currently tested are:
encoding/jsongithub.com/ugorji/go-msgpacklabix.org/v2/mgo/bsoncode.google.com/p/vitess/go/bson
Note that mgo's bson serializer seems to drop some precision with time.Date structs. Uncommenting validation code in the benchmark fails with:
serialization_benchmarks_test.go:156: unmarshaled object differed:

All other fields are correct however.
