So you can’t really blame people doing benchmarks across JSON parsers without realizing the implications of casing because the fact ASP.NET Core has specific defaults that hide away this fact means that you are unlikely to run into the issue all that often.

That literally everytime I’ve written a benchmarking post for C# code, I’ve managed to get something wrong where I didn’t know the compiler would optimize things out etc and someone jumps in the Reddit comments to call me an idiot (Will probably happen with this one too! Feel free to drop a comment below!). Then when you dig a little more in the majority of use cases (case insensitive), it’s not actually that much faster.Īnd I have to point out as well. But I have to admit, there is some level of frustration when moving to using when it doesn’t have the “features” that you are used to in JSON.NET, but it’s touted as being much faster. Why did I make this post in the first place? Was it to crap all over and be team JSON.NET all the way? Not at all. Now again I’m only testing with a very minimal JSON string, but I’m just looking to do a comparison between the two anyway. Wow, credit where credit is due, that’s a very impressive drop. Īnd the results Method Allocated SystemTextCaseInsensitive_Camel 408 B NewtonSoftJson_Camel 3104 B For our test, I’m going to keep the same benchmarking class but just add the MemoryDiagnoser attribute onto it. Memory FootprintīenchmarkDotNet gives us the ability to also profile memory. But what about memory? I hear that touted a lot with the new parser. So now that we are comparing things on an even footing the performance of to NewtonSoft actually isn’t that much better in terms of raw speed. Return (_jsonStringCamelCase) Īnd the results?

With that in mind, I wanted my benchmark to test serializing both PascalCase names (So exact match), and camelCase names. We found it after ToLowering everything. }else if(propertyName.ToLower() = jsonProperty.ToLower()) We found the property on an exact match.

It’s possible that the code would look something like this pseudo code : if(propertyName = jsonProperty) I had a hunch that possibly that even when case insensitivity was turned on, if it could find an exact match first, it would attempt to use that anyway. Now I also had an inkling of a theory this wouldn’t be as simple as first thought. The class I want to deserialize looks like so : public class M圜lass I’m going to use BenchmarkDotNet for this purpose. That is, does deserializing data with case insensitivity turned on slow down the deserialization process. The first thing I wanted to do was create a simple benchmark to test my hypothesis. When everyone’s out there posting benchmarks, are they benchmarking case sensitive or case insensensitive JSON parsing? In another blog post I and many others often refer back to for JSON benchmarks ( ) they are actually doing the case sensitive parsing which again, I don’t think is going to be the reality for the majority of use cases.

By the way, for the record, I think this should be the default behaviour because in 99% of Web SPA cases, the front end will be using javascript which typically is written using camelCase, and if the backend is in C#, the properties are typically written in PascalCase.īut here’s the thing I wondered. So that essentially means when we switch to in an ASP.NET Core project specifically, things will be case insensitive by default, and by extension, have slightly worse performance than forcing things to be case sensitive. ASP.NET Core specifies the settings for camel-casing property names and case-insensitive matching when it uses. If you’re using indirectly by using ASP.NET Core, you don’t need to do anything to get behavior like Newtonsoft.Json. Interestingly enough, there is also the following piece of info : I found this interesting, especially the last line which suggests that doing exact matches by default results in much better performance. The default is case-sensitive, which gives better performance since it’s doing an exact match.

There has been quite a few gotchas and differences between the two libraries, but none more interesting than the following piece of documentation :ĭuring deserialization, Newtonsoft.Json does case-insensitive property name matching by default. NET Core 3+, replacing NewtonSoft.Json (Sometimes called JSON.NET) as the default JSON parser in ASP.NET Core. I’ve recently been trying out the new JSON Parser that is now built into.
