HP-UX Memory File System (MemFS) 2.0

Introducing HP-UX Memory File System (MemFS)

Chapter 1 13

many processes accessing a single buffer. This may have performance implications when
many processes access the same file at the same time.
These limitations will be the focus of future versions of MemFS.
