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