"I looked at bootchart, and ureadahead doesn't get full throughput Even though ureadahead reads everything in one go, and is heavily optimised to read everything in the actual order it's on the disk, it still has to skip over the bits it doesn't need.
This "seek time" is the same performance penalty as finding data in the first place. The only way to avoid this is defragmenting your disk." http://ubuntuforums.org/showthread.php?t=1434502 ** Changed in: ureadahead (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1201114 Title: ureadahead does not fully utilize disk To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ureadahead/+bug/1201114/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
