kandi X-RAY | jsoniter-scala Summary
Scala macros that generate codecs for case classes, standard types, and collections to get maximum performance of JSON parsing and serialization. Latest results of benchmarks on JVMs that compare parsing and serialization performance of jsoniter-scala with AVSystem's scala-commons, Borer, Circe, DSL-JSON, Jackson, ninny-json, Play-JSON, play-json-jsoniter, Spray-JSON, uPickle, weePickle, and zio-json libraries using different JDK and GraalVM versions on the following environment: Intel Core i7-8750H CPU @ 2.2GHz (max 4.1GHz), RAM 16Gb DDR4-2400, macOS Monterey 12.1, and latest versions of Azul Zulu 8/11/17*, GraalVM CE/EE 22.0 for Java 11/17. Latest results of benchmarks on browsers that compares the same libraries on the same environment by the same code which is compiled by Scala.js 1.9.0 to ES 2015 with GCC v20220202 optimizations applied.
