Back when I first tried it, I added noatime (before I knew about relatime), and it did indeed help a lot. Without noatime, the disk seeked heavily and the disk I/O activity (according to the Gnome System Monitor applet) was always high while indexing. With noatime, the disk seeked a lot less, and the disk I/O activity appeared to be nearly zero. When I saw such a dramatic change, I thought that would mean the problems affecting destkop application performance would be fixed. However, despite the lack of much accounted-for I/O, and less noise from the disk, for some reason all applications still ran really slowly. So, yes: noatime/relatime makes a good and essential different on ext3 partitions, and probably others. On latest kernels and newer Trackers, O_NOATIME is I think, so you don't need those mount options. (But relatime is generally a good choice anyway). But: it's not enough by itself, at least on some of our systems. -- Jamie -- Heavy Disk I/O harms desktop responsiveness https://bugs.launchpad.net/bugs/131094 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
