-Describe [FileSystemNotes] here
.
+To get reliability and faster fsck times, make sure the filesystem you are using supports journalling
.
+----
+Older filesystems do a sequential scan through a directory and therefore are excruciating slow dealing with files in a large directory. Splitting the directory up helps, or using reiser or ext3+hdirs fixes this problem.
+----
+If you have a lot of I/O, you may consider turning off atime. This is __not__ recommended for mailspools. This can be done in /etc/fstab with:
+/dev/''partition'' /''mountpoint'' reiserfs notail,noatime 0 3
+----
+reiser can be speed up at a small loss in diskspace by disabling tail compression (as shown in the example above).
