Delphi and Free Pascal bencmark: array vs TList vs dynamic array

Let's perform a simple benchmark testing the random and sequential access to arrays and lists. I would like to compare:

  • static array with predefined size (allocated on stack)
  • TList container class (allocated on heap)
  • dynamic array (allocated on heap)
  • generic Delphi TList or Free Pascal TFPGList (allocated on heap)

I use an array/list of 10M elements of integer and varaint data type. You can change the type definition in "type" section if need to test other cases.
