java-json-benchmark

This project uses JMH benchmark tool to analyse benchmarks of different JSON libraries for Java.

Project requirement

• Java 11
• lombok

So far, JSON libraries tested are:

• Jackson default
• Jackson + Afterburner
• Jackson + Blackbird
• Gson

I've used Yapily API Accounts models to serialize and deserialize which includes time.

Average time (lower the score, the better)
