The best way is to allocate virtual memory with VirtualAlloc, which is not in the heap or on the stack, but retains a chunk of memory directly in the address space of the process.

Comparison of application efficiency

Stack: Automatically allocated by the system, faster. But programmers can't control it.

Heap: Is the memory allocated by new, the best way is to allocate virtual memory with VirtualAlloc, it is not in the heap, not on the stack, but directly in the process of the address space to retain a piece of memory, although the most inconvenient to use, but fast and most flexible.
