- Okay, I'm stupid. I can see the point of a RAM disk during an Install
- to run a root filesystem on temporarily while loading, BUT ... I see no
- point for normal operation. If the ramdisk is SWAPPED then I would
- think you'd be better off just grabbing the data from the hard disk in
- the first place, and skip ram disk. I guess for testing an development
- it's very useful, but as a general tool... I mean if you have main
- memory your program can just grab & manipulate it direct without the
- xtra overhead of maintaining the disk emulation.
-
- As far a "Swapping to Memory instead of disk". This is REALLY dumb. If
- you had the memory in the first place YOU WOULDN't NEED to swap.
-
- Am I missing something here?
