Memory File System (MemFS) 2.0 for HP-UX 11i v3

is a need to wisely use these shared resources. MemFS provides the following tunables
to limit the usage exclusively by MemFS:
• memfs_metamax
Tunable to limit the amount of kernel memory used by MemFS
• memfs_swapmax
Tunable to limit the amount of swap space used by MemFS
For more details on these tunables, see Chapter 2: “Installing, Configuring, Tuning,
and Removing HP-UX Memory File System” (page 15).

1.4 Application Areas for HP-UX Memory File System
Applications that will benefit most from HP-UX MemFS are those that perform mostly
metadata intensive operations like creating and deleting small files and directories.
For example compilers, editors and sorting applications. MemFS never writes metadata
of files to disk, so directory and file manipulation is always a performance gain.
Applications can also interact with MemFS files using the mmap interface.
1.5 Dependencies
Following is a list of patches that are required for MemFS:
