Optimize Directories ( File Access Time ) in ext3 Filesystem

man e2fsck
 
-D    Optimize  directories  in filesystem.  This option causes e2fsck
        to try to optimize all directories, either by reindexing them if
        the  filesystem  supports directory indexing,  or by sorting and
        compressing directories for smaller directories, or for filesys-
        tems using traditional linear directories.
