Ubuntu 9.04 Daily Build Boots In 21.4 Seconds

Posted by timothy on from the spurious-precision-is-2.6-times-better dept.

Pizzutz writes "Softpedia reports that Ubuntu 9.04 Boots in 21.4 Seconds using the current daily build and the newly supported EXT4 file system. From the article: 'There are only two days left until the third Alpha version of the upcoming Ubuntu 9.04 (Jaunty Jackalope) will be available (for testing), and... we couldn't resist the temptation to take the current daily build for a test drive, before our usual screenshot tour, and taste the "sweetness" of that evolutionary EXT4 Linux filesystem. Announced on Christmas Eve, the EXT4 filesystem is now declared stable and it is distributed with version 2.6.28 of the Linux kernel and later. However, the good news is that the EXT4 filesystem was implemented in the upcoming Ubuntu 9.04 Alpha 3 a couple of days ago and it will be available in the Ubuntu Installer, if you choose manual partitioning.' I guess it's finally time to reformat my /home partition..."

    Maybe my math is wrong, but wouldn't that be 1 / (50 Hz) = 20ms?

    For most users, no it will not work. One of the major features of ext4 is extents, which basically reserves space for a file to continue writing at a later date. This will decrease file fragmentation and improve performance.

    If however, you disable extents, then yes you can mount it as ext3. And as you know, ext3 can be mounted as ext2 without the journaling.

    I agree that the win32 ext2 drivers need updating. I would hate to lose access to ext partitions for dual boot systems.
