Disclamer

This test focusses on en/decoding of a cyclefree data structure. Some serializers support cycle detection/object sharing, some offer both modes, some include full metadata, some don’t, some are cross platform, some are language specific, some are text based, some are binary. (See [ToolBehavior](ToolBehavior) )
Other test data will yield in different results. However the results give a raw estimation of library performance.

SIMPLE/GENERIC:
Serializes any POJO tree without class specific optimization. Serialized classes are known in advance. No cycle detection/shared object detection is done.
