This project provides benchmarks comparing the decoding and encoding performance of circe with other open source JSON libraries.
See Benchmark.scala for the benchmark definitions.
The following commands will run the individual benchmarks:
sbt "jmh:run -i 10 -wi 10 -f 2 -t 1 io.circe.benchmarks.ReadingBenchmark"
sbt "jmh:run -i 10 -wi 10 -f 2 -t 1 io.circe.benchmarks.WritingBenchmark"
Here are reading and writing results for circe 0.12.0-M4 on Scala 2.13.0 against Argonaut, JSON4S, Play JSON,
and Spray. The Foos
benchmarks measure encoding and decoding a relatively complex map of case classes with several
members, while the Ints
benchmarks work with a list of integers.

(Note that "reading" here includes both parsing and decoding, while "writing" is encoding and printing. It's also possible to run e.g. decoding or encoding benchmarks individually; see the benchmark source for details.)
All circe projects support the Typelevel code of conduct and we want all of their channels (Gitter, GitHub, etc.) to be welcoming environments for everyone.
