Phoronix: Using Disk Compression With Btrfs To Enhance Performance
Earlier this month we delivered benchmarks comparing the ZFS, EXT4, and Btrfs file-systems from both solid-state drives and hard drives. The EXT4 file-system was the clear winner in terms of the overall disk performance while Btrfs came in second followed by Sun's ZFS in FreeBSD 8.2. It was a surprise that in our most recent testing the EXT4 file-system turned around and did better than the next-generation Btrfs file-system, but it turns out that Btrfs regressed hard in Linux 2.6.35 as to be found in Ubuntu 10.10 and other soon-to-be-released distributions. However, regardless of where Btrfs is performing, its speed can be boosted by enabling its transparent zlib compression support.
