[News] Ext4 and Btrfs Under Linux Put to the Test

Hash: SHA1

The Ext4 Linux file system

,----[ Quote ]
| Ext3, the default Linux file system for many years, is definitely starting to 
| show its age. Modern mass storage devices are approaching its limits and 
| block-based data management is no longer adequate for modern file sizes. High 
| time for an update!   


Testing Out The SSD Mode In Btrfs

,----[ Quote ]
| One month ago we provided benchmarks of the Btrfs file-system and found that 
| while it contained many features to make it a next-generation Linux 
| file-system, its disk performance was rather displeasing. We had found the 
| EXT4 file-system ran faster in a number of the tests and even EXT3 and XFS 
| had their own advantages. Besides offering features like snapshots and online 
| defragmentation, Btrfs has a mode that is optimized for solid-state drives. 
| Will the Btrfs SSD mode cause this new Oracle-sponsored file-system to be the 
| best for non-rotating media? We have benchmarks in this article, but the 
| results may not be what one would expect.        
| [...]
| The Btrfs SSD mode ended out our last test still being slower than not using 
| the SSD mount option. 



Btrfs Benchmarks: Btrfs Is Not Yet The Performance King

,----[ Quote ]
| With the release this week of Fedora 11 Preview, which incorporates
| install-time support for the Btrfs file-system into Red Hat's Anaconda
| installer, we have now delivered our first set of benchmark results for this
| next-generation Linux file-system. Through a horde of disk tests we have
| looked at the Btrfs file-system performance and compared it to that of EXT3,
| EXT4, and XFS. While Btrfs does perform well in some areas, it is not yet the
| performance king for Linux file-systems. As our results show, in some tests
| it even has a hard time competing with the incremental EXT4 file-system.


Linux Don't Need No Stinkin' ZFS: BTRFS Intro & Benchmarks

,----[ Quote ]
| ZFS may be locked into the Solaris operating system but “Butter FS” is on the
| horizon and it’s boasting more features and better performance.


Kernel 2.6.29: Corbet Says Btrfs Next Generation Filesystem

,----[ Quote ]
| Linux kernel developer Jonathan Corbet has just previewed the features of the
| upcoming Linux Kernel 2.6.29 that includes Btrfs, which he claims is the
| filesystem of the future.


Btrfs Merged Into Mainline Linux Kernel

,----[ Quote ]
| Btrfs, the next-generation Linux file-system conceived by Oracle and designed
| to compete with some of the features found in Sun's ZFS file-system, has just
| been merged for the Linux 2.6.29 kernel.


The Evolution Of An GNU Project

,----[ Quote ]
| First lets be honest GnoMenu is a fork of another project the "Gnome Vista
| Start Menu" by Chris Hughes. Most hard core Linux users looked at the menu
| Chris did as a cheap Vista look alike. In some ways it was but Chris also
| stated that other menu designs were possible yet no one really bothered to
| pay attention. Well almost nobody. Enter Helder Fraga who took Chris' work
| and forked it into GnoMenu.


Appeal for BtrFS Inclusion in Kernel

,----[ Quote ]
| Chris Mason, lead developer of the copy-on-write BtrFS filesystem, has
| appealed for its inclusion in the Linux kernel.

Version: GnuPG v1.4.9 (GNU/Linux)
