JSON serialization benchmarks

Methodology

Participants:

For testing were selected data with different structure:

  • citys - A large array (29470 items) of simple objects. The compact json representation takes about 2.5 MB.
  • repos.json - An array of four objects with complex structure. The compact json representation takes about 342.8 kB.
  • user.json - one object with a complex structure. The compact json representation takes about 4.2 kB.
  • response.json - one object with a simple structure. The compact json representation takes about 425 B.

Serialization was tested in two versions:

  • pojo - Objects were presented as a POJO objects.
  • maplist - Objects were presented as Map-s.

On deserialization were tested only transformation from String into Map-s.

Build and Run

./gradlew clean && ./gradlew shadow -DgroovyVersion="2.3.0-rc-2" && java -jar target/benchmarks.jar ".*Benchmarks.*"

You can specify Groovy version via JVM argument.

Where serialization points = throughput / maxPointsInGroup * 500 (500 for pojo and 500 for maplist) and deserialization points = throughput / maxPointsInGroup * 1000.
