- I've been wondering about this.
-
- I've just reinstalled my linux system on a machine with 12Mb of
- memory, and didn't enable any paging space on disk.
-
- However, with dynamic buffercache, would it still be beneficial to
- have at least a small amount of swapspace, even if my memory
- requirements don't exceed the capacity of silicon?
-
- Will Linux (0.97.1+) page out old data pages in favour of buffer blocks?
-
- I'm thinking of things like login shells that start up emacs and then
- do nothing for the next several days, or processes that get left idle
- on far-away, forgotten VC's. The text pages are quite possibly going
- to be shared, and paged from the executable anyway, but what about
- data? A large, forgotten emacs buffer? A memory-intensive program or
- perl script stopped for debugging, while compilation goes on
- elsewhere?
