HikariJSON
A High-performance JSON parser.
HikariJSON is targeted exclusively at Java 8. If you need legacy support, there are several decent libraries available.
JMH Benchmarks<br/> Microbenchmarks were created to isolate and measure the performance of popular JSON libraries using the JMH microbenchmark framework developed by the Oracle JVM performance team. You can checkout the HikariJSON benchmark project for details and review/run the benchmarks yourself.
Note: These are extremely early results and do not reflect our final goals.
