- I will not claim to be to knowlegdable about ram disk, io, etc., but it
- seems to me, you are saying:
-
- 1. Make a ram disk.
- 2. Put your swap there. This gives no disk i/o if you have enough memory.
-
- If this is true, and you have enough memory for a ram disk to contain all of
- the swapped data, would you need to swap if you used the memory for real
- memory instead of a ram disk? Why use up memory for a ram disk, that will
- just force you to swap to the ram disk more, right????
-
- Am I missing something here?
