- People that do this should know two things:
-
- 1 -- Swapping on a file is NOT as fast as swapping on a raw partition.
- Theorertically they should be the same, but the vnode system doesn't
- have the ability to pass all the information one would need to make
- them the same speed. Therefore, expect a small slow-down.
-
- 2 -- SunOS 4.1.x has a bug when swapping on a file. If a very, very
- large program (we're talking >120meg) exits on such a system, it
- will take considerably longer than if you were using raw partitions.
- Sun has a patch for this, but it's not supported.
