“We tested out these five Linux file-systems with their
default mount options using Ubuntu 10.04 LTS Alpha 1 with its Linux
2.6.32 kernel. Our test system this time around was an Intel Core
i7 920 quad-core processor with Hyper Threading that was clocked at
3.60GHz, the ASRock X58 SuperComputer motherboard, 3GB of DDR3
system memory, a GeForce 9800GTX graphics card, and the
file-systems were tested on a solid-state drive that was the OCZ
Agility EX 60GB.“Using the Phoronix Test Suite we ran the Dbench, IOzone,
SQLite, PostMark, Threaded I/O Tester, Gzip, and FS-Mark test
profiles. Besides the EXT4 change in the Linux 2.6.32 kernel, the
Btrfs file-system in this most recent kernel release now has proper
snapshot and sub-volume deletion support (along with the ability to
rename snapshots and sub-volumes), discard support for SSD devices,
and there are performance improvements too.”
