Hello.. About C++ and Delphi and FreePascal generic (template) style containers.. Generics.Collections of Delphi and FreePascal for generic (template) style containers that you can download from here: https://github.com/maciej-izak/generics.collections TList of Generics.Collections of Delphi and FreePascal is implemented the same as STL C++ Vectors: they are array-based. And since data structureS are the same then also performance should be comparable. So I've done a small test between Tlist of Generics.Collections of Delphi and FreePascal and C++ vector, it's an addition of 3000000 records of 16 byte length, in one loop, here is the results: Tlist time = 344ms Vector time = 339ms It seems they are the same, the test use only the function ( List.add , vector.push_back). STL vectors with the at() and Delphi TList of Generics.Collections of Delphi and FreePascal perform bounds checking. Thank you, Amine Moulay Ramdane.
