Since 19 December 2001, the GENERIC kernel from RELENG-4 has included
'options UFS_DIRHASH', as documented in LINT:
# Directory hashing improves the speed of operations on very large
# directories at the expense of some memory.
options UFS_DIRHASH
See the original announcement in http://docs.freebsd.org/cgi/getmsg.cgi?fetch=18975+0+archive/2001/freebsd-fs/20010624.freebsd-fs
So, no, that shouldn't be a problem.
Cheers,
Matthew
