Performance in comparison to other Frameworks

[ETSPMeder]

I'm looking for a fast way to serialize and deserialize my JSON from and to objects. I used the TJSON Class from Delphi for that, but when it comes to more data, it gets very slow. I tested a bit and wanted to share my results for everyone who is interested:

JSON object with 100,000 elements in an array. The class inherits from a main class, so the JSON is not extra simple but could also be more complex.

Test on Windows 32 Bit

Serialization

• TJSON = 2885 ms
• Quicklib = 779 ms
• Neon = 1064 ms

Deserialization

• TJSON = 15987 ms
• Quicklib = 2104 ms
• Neon = 1214 ms

Test on Windows 64 Bit

Serialization

• TJSON = 2427 ms
• Quicklib = 854 ms
• Neon = 1009 ms

Deserialization

• TJSON = 10575 ms
• Quicklib = 2164 ms
• Neon = 1244 ms

Test on Android Pixel 7a

Serialization

• TJSON = 10450 ms
• Quicklib = 3036 ms
• Neon = 4016 ms

Deserialization

• TJSON = 59530 ms (~1min 😮)
• Quicklib = 8240 ms
• Neon = 5312 ms

As you can see, on serialization, Quicklib is a bit faster than Neon (~20%), while on deserialization, Neon is faster than Quicklib (~40%). Unfortunately, I was not able to get mORMot2 to run under Mobile. The performance of mORMot2 under Windows was breathtaking: 55ms for deserialization.

But in my opinion, Neon has some more benefits in comparison to the other frameworks:

1. There is not much extra code that has to be added into the project.
2. The syntax is nearly identical to TJSON, so you just have to replace TJSON with TNeon, add Neon.Core.Persistence.Json to the uses, and you're good to go.
3. It works with Windows and mobile
