EXT4, Btrfs, NILFS2 Performance Benchmarks
Phoronix: EXT4, Btrfs, NILFS2 Performance Benchmarks
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.
