Is There a Perfect Linux Filesystem?
,----[ Quote ]
| Most often, when someone talks about a filesystem or file system, they're
| referring to disk filesystems such as NTFS, FAT, ext2, ext3, ext4, ISO 9660
| and many others but can also refer to network file systems such as CIFS
| (Common Internet File System aka Samba) and NFS. A filesystem is a
| specially-designed database of files, their disk location, definition and
| attributes. Everything on a Unix or Linux filesystem is a file: Directories,
| processes, links, programs, and device references. All files.

EXT4, Btrfs, NILFS2 Performance Benchmarks
,----[ Quote ]
| The past few Linux kernel releases have brought a number of new file-systems
| to the Linux world, such as with EXT4 having been stabilized in the Linux
| 2.6.28 kernel, Btrfs being merged into Linux 2.6.29, and most recently the
| NILFS2 file-system premiering with the Linux 2.6.30 kernel. Other
| file-systems have been introduced too during the past few Linux kernel
| release cycles, but these three have been the most talked about and are often
| looked at as being the next-generation Linux file-systems. Being the
| benchmarking junkies that we are, we have set out to compare the file-system
| performance of EXT4, Btrfs, and NILFS2 under Ubuntu using the Linux 2.6.30
| kernel. We also looked at how these file-systems compared to EXT3 and XFS.

| As we’ve demonstrated over the past several weeks, there are no shortage of

FS-Cache merged in Kernel 2.6.30
,----[ Quote ]
| FS-Cache has been merged into the upcoming kernel 2.6.30. This allows for a
| generic caching interface in the kernel for other file systems. For example,
| you can use local hard disks to cache data accessed via NFS, AFS, or CD-Rom.
| Since these tend to be high-latency while the disks are low latency, it
| should provide for a nice speedup.
