"inode table" is also > fairly extN-specific. How about somethign like "This mount significantly reduces writes needed to update the inode's timestamps, especially mtime and actime. Examples of workloads where this could be a large win include frequent random writes to preallocated files, as well as cases where the MS_STRICTATIME mount option is enabled."? (The advantage of MS_STRICTATIME | MS_LAZYTIME is that stat system calls will return the correctly updated atime, but those atime updates won't get flushed to disk unless the inode needs to be updated for file system / data consistency reasons, or when the inode is pushed out of memory, or when the file system is unmounted.) - Ted _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
