Maintaining filesystem efficiency
Three aspects of filesystem usage can degrade the efficiency of filesystems.
NOTE:
With the exception of limiting directory size,
most of the information that follows
does not apply to HTFS and
DTFS filesystems and is marked accordingly.
Disk fragmentation-
Disk fragmentation is the scattering of available disk space
caused by constant use and reuse of filesystem blocks.
See
``Reducing disk fragmentation''.
Excessively large directories-
Directories that contain large numbers of files
(regardless of file size) increase the system search time for files
within the directory.
See
``Monitoring and limiting directory sizes''.
Empty directory slots-
Empty directory slots, caused by large numbers of files being created
and moved or removed from a directory can also cause the directory
to become too large
(EAFS, AFS, and S51K filesystems only).
See
``Removing empty directory slots''.
