Compares performance of several JSON parsers used in Scala:
- argonaut
- borer
- circe
- jackson with scala module
- json4s with jackson
- json4s native
- play-json, used in Play Framework
- sphere-json
- spray-json
- jsoniter-scala
- uPickle
- weePickle
- refuel-json
The test case is to deserialize a json into a case class and to serialize back to json.
The performances are measured with JMH
