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)
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?
