“Earlier this week we published extensive benchmarks of
EXT4 that looked at the performance of this Linux file-system under
every major kernel release since it was declared stable in the
Linux 2.6.28 release. EXT4 has encountered many significant
performance losses over time as its developers batten up the data
security, but there have been some improvements too. At the same
time though the developers working on the still-experimental Btrfs
file-system continue to move along and push forward changes with
each kernel cycle. Just last month we delivered Btrfs comparative
benchmarks using the Linux 2.6.32 kernel, but already out of our
own personal interest and requests from readers, we have new tests
atop the latest Linux 2.6.33 kernel.“Our 2.6.32 file-system benchmarks compared the performance
directly of EXT3, EXT4, XFS, ReiserFS, and Btrfs. These results
remain relevant so check them out if you are interested in the
performance of these other Linux file-systems. For this article we
are simply comparing the performance of the EXT4 and Btrfs
file-systems using the Linux 2.6.33-rc4 kernel.“The test system is the same ASRock ION 330HT-BD NetTop that we
used earlier this week with a dual-core Intel Atom 330 with Hyper
Threading, ASRock AMCP7AION-HT motherboard with NVIDIA’s MCP79
Chipset, 2GB of system memory, a 320GB Seagate ST9320325AS hard
drive, and NVIDIA ION (GeForce 9400M) graphics. Ubuntu 9.04 x86_64
was the distribution running with X Server 1.6.0, xf86-video-nv
driver, GCC 4.3.3, and the Linux 2.6.33-rc4 kernel from Ubuntu’s
mainline kernel PPA.”
