I hadn't heard this. I don't know why that would be true. } We should probably refuse to use } bth at the same time. noatime seems to be unnecessary with SU anyway. If you are reading lots of files and writing lots of files on the same disk, it would seem to improve performance if you avoiding writing back the inodes of files that had only been read. If you are only reading files on the filesystem, I don't see where softupdates buys you any performance increase, whereas noatime does.
