mORMot 2 Generics Collections: Fast, Small & Scalable

A recent discussion on Delphi-PRAXiS highlighted this issue through a comprehensive benchmark comparing the Delphi RTL, Spring4D, and mORMot 2 generics collections.

Trying to compile 500 records + 2000 generic specializations shows very clearly why mORMot 2 generics collections are an excellent choice for serious Delphi - or FPC - projects.

mORMot 2 Highlights

• Extremely fast compilation even with thousands of specializations
• Smallest binary size
• Very reasonable memory consumption during compilation
• Thread-safe dictionaries with advanced features like JSON/binary serialization out of the box
• Delphi and FPC compatibility

If your project suffers from long compile times or huge executable size because of heavy generic usage — mORMot 2 collections (mormot.core.collections) is currently the most scalable and efficient solution available in the Delphi ecosystem.

Give it a try — the difference is usually noticeable from the first clean build.

Thanks Waldemar for the insights, and also thanks Valerii for the adorable marmot in the above picture.
