 The `JsonSerdeBenchmark` benchmark measures the average time taken to serialize a simple Java object, including polymorphism, to JSON and back,
 validating the intermediate JSON data on both legs of the journey.

+This is a more real-world test, keeping to the basics of what's possible with JSON schemas, as that's what most use-cases need. 
+Therefore, this benchmark includes the cost of serialization, deserialization and two validations of the JSON document.
+JSON (de)serialization is generally handled by Jackson, except where this isn't compatible with the validation implementation.
+The cost of just Jackson (de)serialization is included, i.e. no validation, in the results below for comparison.

-At the time of writing, `Medeia` comes as a clear winner for speed, with `Everit` not far behind.

+At the time of writing, `Medeia` comes as a clear winner for speed, with `Justify` and then `Everit` not far behind.
+Unfortunately, `Medeia` and `Justify` look to no longer be maintained, and `Everit` is deprecated in favour of a new implementation that seems both incomplete and slower.
 Plus, neither of them handle the latest drafts of the JSON schema standard.
-If `Medeia` and `Everit` are excluded, then the clear winner is `SchemaFriend`.
+If these three are excluded from the results, then the clear winner is `SchemaFriend`.
