Hackosis博客注意到Linux创建者Linus Torvalds和一位程序员之间的一段有争议的对话，这位程序员发现禁用atime选项（将最后一次访问时间写入Linux系统访问的每个文件）会带来一些显著的性能改进。如果你不使用任何依赖atime的碎片整理或邮件查看应用程序（如mutt），你至少可以尝试禁用atime，如果出现问题，可以切换回原来的状态。请继续阅读有关如何在Linux桌面上执行此操作的简单说明。

• Open a terminal program and give yourself super-user (i.e. sudo) permissi***. On some systems, that's typing sudo -i, on others it's su -.

  Back up your original hard-drive-configuring fstab file. On Ubuntu, that's accomplished with something like this:

  cp /etc/fstab /etc/fstab.original

  Open the fstab file in your text editor of choice, be it gedit in GNOME, Kate in KDE, or nano or pico if you're happier in text only. Using gedit would be this command: gedit /etc/fstab

  Look through the file for the partition line that contains your main system, not your swap partition. You'll likely see "ext3" on that line, instead of "ntfs" or "swap" or the like. Note the two numbers—usually 0 and/or 1s—at the end of that line, and the section just before them, which should list a series of hard drive opti*** like relatime,errors=remount-ro.

  At the end of that comma-separated string, add these two items, making sure to place a comma before them:

  noatime,nodiratime

  Save the fstab file, reboot your system. If anything seems busted or wonky, you can copy your fstab file back over and reboot:

  sudo cp /etc/fstab.original /etc/fstab

我已经在我的Ubuntu 8.04分区上试过了，感觉有了一些改进，尽管所有的东西都是硬盘，很难确定。如果你注意到一些真正的**，或者根本没有，请在评论中告诉我们。
