Specify the minimum time in milliseconds required to initiate another
disk transfer on the same cylinder.
Modern disks with read/write-behind achieve higher performance without
this feature,
so it is best to leave it at 0 milliseconds.
.It Fl d Ar max-extent-size
The file system may choose to store large files using extents.
This parameter specifies the largest extent size that may be
used. It is presently limited to its default value which is 16
times the file system blocksize.
