Yes. It is proportional to the number of inodes (data to be processed),
number of cylinder groups (number of zones to seek between) and the
complexity of the namespace. With IFS, for example, the fsck time is
far from the level it is in FFS. This is simplified, though, of course.
Other things come into it as well.
