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.
