CLASS vs. OBJECT and memory management

[JC_]

Here is a little benchmark for Delphi I did.

https://github.com/turric4n/Delphi-B...jectsVSRecords

Records are more faster than Heap allocated Records (Pointer to Records) and much more faster than Objects.

It's tricky, I have similar tests and results depends on:
1) How many records/objects exists
2) Complexity of record/object (number or variables)
The results will be completely different with:

  TSpriteRec = record
    ID         : integer;
    x, y    : integer;
    Name    : String[80];
    angle     : double;
    alpha     : byte;
    components : array [0..9] of integer;
    p          : pointer;
  end;

3) If features like sorting are needed

In general array of pointers is fastest.
