Yes, typically - XFS uses its internal "bulkstat" code to speed up
the inode scanning process (and it only needs to be done once, on the
initial mount, and then XFS "remembers" that the check has been done,
for subsequent mounts and it journals all updates to the quota files),
whereas the userspace quotacheck(1) program is filesystem independent
(IIRC) and doesn't implement such optimisations.
FWIW, quotacheck time is a function of the number of inodes in the
filesystem, not the number of users.
cheers.
