Performance testing of serialization and deserialization of Java JSON libraries

Benchmark of Java JSON libraries

Purpose

This project benchmarks the throughput performance of a variety of Java Json libraries using JMH. It covers the following libraries:

• jackson
• yasson

Changes of this fork

The project is a fork of https://github.com/fabienrenaud/java-json-benchmark with the following changes:

• Updated versions of aforementioned frameworks
• Removed jsoniter references which no longer successfully test under JDK 11

Results

The benchmarks are written with JMH and for Java 11.

The results here-below were computed on 15 January 2020 with the following libraries and versions, using Amazon Corretto JDK 11.0.5 on a Intel(R) Core(TM) i7-4700MQ CPU @ 2.40GHz and a 2GB heap.

Framworks tested:

Library	Version
jackson	2.10.1
yasson	1.0.5

Serialization

./run ser --apis databind --libs yasson,jackson --datatype users
