Still confused about 50% requirement

24 Views

I am still confused about the 50% requirement for better performance.

According to the Note 917803: "Memory requirement of the main memory: Due to temporary indexes and the memory management unit, the main memory requirement may increase to a maximum of twice the size.",

if my index size is 20GB:

1) do I need a physical memory of 40GB (twice the index size)

or

2) do I need a physical memory of 80GB (twice the index size and taking into account 50% requirement).

If the second one is correct, then it implies 4 times the index size is required, effectively shelling 4 times more for licenses.

Which one is correct?
