> but its rarely gb at the same time. Thats the point. Its a dumping ground for stuff thats not used very often. But it has to be GB to actually make a difference. If your swap is not full of GB of data, then obviously you don't need it (or it just becomes a reserve when you are in an OOM situation - but this is where you don't want to be with swap avaible either) |

I think the parent meant, that it barely needs to be read / write GBs at the same time. Not that that much swap is never being in use at the same time.
So you can use a lot of swap, but will never need to read it back in all at once.
