Yes, XFS doesn't journal data in any way, AFAIK. I don't know how one could
go about speeding up fsyncs() with it.
What I *do* know is that I don't trust spools to XFS, because anything not
fsync()'ed upon crash WILL be lost, but the metadata will likely be there
and it is a total bitch to find out what has been damaged. You will have to
hunt the entire fs over for files containing while blocks of NULs.
