I use this regularily (well, -CURRENT). I have no numbers, but performance
is ok. I have the home directories on a W2003k server and it 'feels' fast
The only problem I see is a lot of 'file server not reponding' and 'file
server up again' (with 2-3 seconds in between). This is usually when
saving a large mail from pine. Linux clients see the same problem, so I
suppose it is a problem on the SFU side. Locking seems to work. Problems
are with filenames that are illegal for NTFS - hosting a 2.11BSD source
tree on a W2003 NFS share does not work because of filenames containing
':' :-). I've not tested what other characters are illegal.
Another problem is that on the NTFS side there is no good way to backup,
copy, whatever the trees, because while NTFS handles Makefile and
makefile, no Windows tool can access both of them. Even worse thinks like
ADSM backup sometimes die with internal errors.
Mapping of UIDs and GIDs is rather magic. The FreeBSD side, the SFU tools
and cygwin all see different numbers which is rather annoying. The same is
with symbolic links.
The file flags are not supported by the server. There are no extensions
that I know of.
