微软的Serialize和Newtonsoft的SerializeObject比较

微软的序列化反序列化组件出来已有好几年了，刚出来的时候各种吐槽。最近在优化代码，比较了一下微软的Serialize和Newtonsoft的SerializeObject，感觉大部分场景下可以用微软的序列化组件了，Newtonsoft第三方可能被我放弃掉。测试有交换顺序，也有多次测试。当然如果加上JsonSerializerOptions，而且全部配置起来性能就会有所下降，毕竟这么多配置在这呢，但是这样也会更加灵活。
初步结论，在使用微软默认配置下数据量大序列化速度比Newtonsoft快了一倍。

微软文档里面有各种介绍，不再详述！
从 Newtonsoft.Json 迁移到 System.Text.Json – .NET | Microsoft Docs
