I don't think this can be advocated as a real solution to performance problems. This can mean data loss for some applications like email that expect "fsync return" to mean "this data is safely on disk". May as well say "I improved the performance of my backups by writing to /dev/null". Cheers, Andreas -- Andreas Dilger Principal Software Engineer Cluster File Systems, Inc.
