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)
Other test data will yield in different results. However the results give a raw estimation of library performance.
