Newer Results on Different Hardware
(This is the benchmark for JDK8 on linux, the benchmark for JDK11 is done on macos to keep consist with previous hardware and the results are placed on wiki/Home)
OS:Linux
JVM:Oracle Corporation 1.8.0_331
CPU:null os-arch:null
Cores (incl HT):8
This test focusses on en/decoding of a cyclefree data structure, but the featureset of the libraries compared differs a lot:
- some serializers support cycle detection/object sharing others just write non-cyclic tree structures
- some include full metadata in serialized output, some don’t
- some are cross platform, some are language specific
- some are text based, some are binary,
- some support versioning forward/backward, both, some don’t
(See ToolBehavior)
Other test data will yield different results (e.g. adding a non ascii char to every string :-) ). However the results give a raw estimation of library performance.
Benchmarks serializers
- Only cycle free tree structures. An object referenced twice will be serialized twice.
- no manual optimizations.
- schema is known in advance (pre registration or even class generation). (Not all might make use of that)

Contains serializer(-configurations)
- supporting full object graph write/read. Object graph may contain cycles. If an Object is referenced twice, it will be so after deserialization.
- nothing is known in advance, no class generation, no preregistering of classes. Everything is captured at runtime using e.g. reflection.
- note this usually cannot be used cross language, however JSON/XML formats may enable cross language deserialization.

- cycle free, schema known at compile time: protostuff, fst-flat-pre, kryo-flat-pre. (note: protostuff uses class generation while the other two just require a list of classes to be written)
- cycle free, schema UNKNOWN at compile time: fst-flat, kryo-flat, protostuff-runtime, msgpack/databind
- full object graph awareness, schema UNKNOWN at compile time: fst, kryo.
