isn't O_NOATIME per file open[1]? (while the mount option is per mount point afaik.) this might be a bit of performance drop in some cases using. 1. http://www.kernel.org/doc/man-pages/online/pages/man2/open.2.html O_NOATIME (Since Linux 2.6.8) Do not update the file last access time (st_atime in the inode) when the file is read(2). This flag is intended for use by indexing or backup programs, where its use can significantly reduce the amount of disk activity. This flag may not be effective on all file systems. One example is NFS, where the server maintains the access time.
