How to improve JSON deserialization speed in .Net? (JSON.net or other?)

Question

We\'re considering replacing (some or many) \'classic\' SOAP XML WCF calls by JSON (WCF or other) calls, because of the lower overhead and ease of use directly in Javascript

Answer 1

I'm adding 2 more points here, which help me to improve my IoT application performance. I was receiving millions of JSON messages every day.

1. Changes in ContractResolver instance

Old code

return JsonConvert.SerializeObject(this, Formatting.Indented,
                          new JsonSerializerSettings
                          {
                              ContractResolver = new CamelCasePropertyNamesContractResolver()
                          });

New Code

Not creating contract resolver instance on every call, Instead using a single instance

return JsonConvert.SerializeObject(this, Formatting.Indented,
                          new JsonSerializerSettings
                          {
                              ContractResolver = AppConfiguration.CamelCaseResolver
                          });

2. Avoid creating JObject

Old Code

JObject eventObj = JObject.Parse(jsonMessage);
eventObj.Add("AssetType", assetType); //modify object

JObject eventObj2 = JObject.Parse(jsonMessage);
eventObj.Add("id", id); //modify object

NewCode

JObject eventObj = JObject.Parse(jsonMessage);
eventObj.Add("AssetType", assetType); //modify object

JObject eventObj2 = (JObject)eventObj.DeepClone();
eventObj.Add("id", id); //modify object

To check performance benefits, I used benchmarkdotnet to see the difference. check this link as well.
