JSON-B Benchmark Project

This project benchmarks JSON-B RI and Jackson operations. Scores are in throughput (ops/ms)

Running Benchmarks

mvn clean install exec:java -Dexec.mainClass="org.istanbuljug.json.RunBenchmarks"

Benchmark #1

Java Object to JSON

Jug jug = new Jug("İstanbul JUG", 2010);

//JSON-B
Jsonb jsonb = JsonbBuilder.create();
String json = jsonb.toJson(jug);

// Jackson
ObjectMapper objectMapper = new ObjectMapper();
String json = objectMapper.writeValueAsString(jug);

Result #1

Benchmark #2

JSON to Java Object

String jug = "{\"name\":\"İstanbul JUG\",\"year\":2010}";

//JSON-B
Jsonb jsonb = JsonbBuilder.create();
Jug jug = jsonb.fromJson(jug, Jug.class);

// Jackson
ObjectMapper objectMapper = new ObjectMapper();
Jug jug = objectMapper.readValue(jug, Jug.class);
