Which one is fast and efficient to use
Fvault or Nvault?

[HamletEagle]

Nvault does everything you need?
If yes, use nvault.

[Bugsy]

nVault is more efficient as FVault stores data in plain text and a ton of natives are called for a transaction. nVault is module based and uses a hashed key for lookup.

if you want to do more things after saving, i think its important to tell its better to use sql(lite) for example. especially talking about ranking and showing top15 (didnt say its imposs with nvault...)
