Multimedia streaming is an obvious one.
assuming a single reader? or multiple readers at the same spot?
For databases, it depends on the application, but in general the
database will do a better job of selecting which data to keep in
memory than the file system can. (Of course, some low-end databases
rely on the file system for this.)
Yeah, but from what i've heard is that the database will start up
asking for a chunk of memory (and get it). The ARC will then react
accordingly to what memory is left and not grow too big to cause the
database to "shrink" its memory hold.
