The Newest Java Json Benchmark Results just dropped

• DSL-JSON

  6 987 5.2 Java

  High performance JVM JSON library

  

Afaik dsl-json came up with a lot of improvements and inspired a several other libraries like JsonIter and jsonIter-scala. Jsoniter-scala by u/plokhotnyuk is probably the most optimized JSON library on the JVM at this point, and seems to power most of the Scala ecosystem. Some implementations/optimizations eventually made their way back into Jackson and other libraries.

• java-json-benchmark

  5 928 6.0 Java

  Performance testing of serialization and deserialization of Java JSON libraries

• InfluxDB

  www.influxdata.com featured

  Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  

• fastjson

  3 25,635 1.5 Java

  FASTJSON 2.0.x has been released, faster and more secure, recommend you upgrade.

• Gson

  27 22,981 9.1 Java

  A Java serialization/deserialization library to convert Java Objects into JSON and back

  

Gson has been in maintenance mode for at least 6 years. It's kind of a shame, because the API and implementation were a lot cleaner than Jackson.

• jsoniter-scala

  29 710 9.6 Scala

  Scala macros for compile-time generation of safe and ultra-fast JSON codecs
