Ubuntu 9.04 boots in 21.4 seconds

Softpedia reports that Ubuntu 9.04 Boots in 21.4 Seconds using the current daily build and the newly supported EXT4 file system.

The article provides some interesting test results, as you can see below:
· Ubuntu 8.10 with EXT3 filesystem boots in 31.8 seconds (on the AMD Sempron system);
· Ubuntu 9.04 Alpha (Build 20090112.1) with EXT3 filesystem boots in 28.3 seconds (on the AMD Sempron system);
· Ubuntu 9.04 Alpha (Build 20090112.1) with EXT4 filesystem boots in 23.1 seconds (on the AMD Sempron system).

· Ubuntu 8.10 with EXT3 filesystem boots in 26.8 seconds (on the Intel Core 2 Duo system);
· Ubuntu 9.04 Alpha (Build 20090112.1) with EXT3 filesystem boots in 24.5 seconds (on the Intel Core 2 Duo system);
· Ubuntu 9.04 Alpha (Build 20090112.1) with EXT4 filesystem boots in 21.4 seconds (on the Intel Core 2 Duo 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. The bad news is that EXT4 will not be the default filesystem for the Ubuntu OS until version 9.10, due for release in late October this year.

Linux hardware site Phoronix has released benchmarks based on extensive Ext4 performance testing that was conducted with a solid-state drive. The most impressive results can be seen in the IOzone test, which measures write performance for a large file. In this test, Ext4 annihilated the competition and significantly outperformed XFS, JFS, ReiserFS, and Ext3. The new filesystem also outpaced its peers in the Intel IOMeter File Server Access Pattern Test.
