Buttering Up Linux File Systems
,----[ Quote ]
| Interestingly, BTRFS was initially developed by Oracle (NASDAQ: ORCL) â which
| is acquiring Sun â but is now licensed under the GPL and is thoroughly in the
| open source community, open for contribution from anyone. It is described on
| its own project pages as "a new copy on write file system for Linux aimed at
| implementing advanced features while focusing on fault tolerance, repair and
| easy administration."

Kernel Log: X server 1.7 delayed; Compiz runs on newer Radeon GPUs; DRBD in
kernel soon
,----[ Quote ]
| Although some X.org drivers have been updated for X server 1.7, development
| work is running behind schedule. New drivers from AMD, Intel and Nvidia and
| new Linux versions mean a number of corrections and enhancements in the
| graphics system. 3D support for newer Radeon GPUs is now adequate for Compiz.
| DRBD should make it into the main Linux kernel development tree in 2.6.32.

A short history of btrfs
,----[ Quote ]
| Btrfs is heading for 1.0, a little more than 2 years since the first
| announcement. This is much faster than many file systems veterans - including
| myself - expected, especially given that during most of that time, btrfs had
| only one full-time developer. Btrfs is not ready for production use - that
| is, storing and serving data you would be upset about losing - but it is
| ready for widespread testing - e.g., on your backed-up-nightly laptop, or
| your experimental netbook that you reinstall every few weeks anyway.

Choosing the right Linux File System Layout using a Top-Bottom Process
,----[ Quote ]
| As you may probably know, Linux supports various filesystems such as ext2,
| ext3, ext4, xfs, reiserfs, jfs among others. Few users really consider this
| part of a system, selecting default options of their distribution's
| installer. In this article, I will give some reasons for a better
| consideration of the file-system and of its layout. I will suggest a
| top-bottom process for the design of a ``smart'' layout that remains as
| stable as possible over time for a given computer usage.

The Btrfs file system
,----[ Quote ]
| Btrfs, the designated "next generation file system" for Linux, offers a range
| of features that are not available in other Linux file systems â and it's
| nearly ready for production use.

Btrfs v0.19 Brings Some Gains, Some Losses
,----[ Quote ]
| As we shared early on in this article, the Btrfs v0.19 notes mention, "In
| general, v0.19 is a dramatic speed improvement over v0.18 in almost every
| workload." From our Btrfs file-system tests today, this is partially true. We
| encountered several tests where there were indeed hefty speed-ups in
| performance with the Serial ATA 2.0 SSD being tested, but in other tests,
| there was a very evident drop in performance. Specifically, the write
| performance always seemed to be better, but that was not always the case for
| the read performance. There was generally a 14~16% drop in performance when
| this problem occurred. Granted, due to the differing kernels and just not the
| Btrfs difference, this could be attributed to something else within the Linux
| kernel, but nevertheless this does show some signs of problems with the
| newest Linux code.

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.

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.
