 I'll list serveral executed results.


In .net NewtonJson is faster than  System.Text.Json.JsonSerializer.Serialize.The  validated result as below.


1.


NewtonJsonDemo cost 1290 milliseconds.
JsonSerializerDemo cost 1404 milliseconds.


 2.


NewtonJsonDemo cost 1213 milliseconds.
JsonSerializerDemo cost 1814 milliseconds.


3.


NewtonJsonDemo cost 1305 milliseconds.
JsonSerializerDemo cost 1373 milliseconds.


4.


NewtonJsonDemo cost 1329 milliseconds.
JsonSerializerDemo cost 1749 milliseconds.


5.


NewtonJsonDemo cost 1234 milliseconds.
JsonSerializerDemo cost 1395 milliseconds.


While  in .net core 3.0 System.Text.Json.JsonSerializer.Serialize is faster than NewtonJson.


1.


NewtonJsonDemo cost 1704 milliseconds.
JsonSerializerDemo cost 1247 milliseconds.


2.


NewtonJsonDemo cost 1596 milliseconds.
JsonSerializerDemo cost 1451 milliseconds.


3.


NewtonJsonDemo cost 1430 milliseconds.
JsonSerializerDemo cost 1221 milliseconds.


4.


NewtonJsonDemo cost 1390 milliseconds.
JsonSerializerDemo cost 1219 milliseconds.


5.


NewtonJsonDemo cost 1334 milliseconds.
JsonSerializerDemo cost 1216 milliseconds.



Totally speaking, the .net core is completely faster than .net both in NewtonJson and System.Text.Json.JsonSerializer.Serialize


The data source come from Adventureworks2017.Sales.SalesOrderDetail table which has 121317 rows .
