# json-performance-benchmarks
2-
Collection of jmh-based benchmarks that compare performance Java JSON libraries for reading, writing
1+
# Overview
2+
3+
This project contains a set of performance micro-benchmarks, based on excellent
4+
[JMH](http://openjdk.java.net/projects/code-tools/jmh/) package.
5+
Benchmarks exercise JSON reading and/or writing performance of a few popular Java JSON libraries:
6+
7+
* [https://github.com/FasterXML/jackson](Jackson)
8+
* [https://github.com/google/gson](GSON)
