Benchmarking ZFS On FreeBSD vs. EXT4 & Btrfs On Linux

"ZFS is often looked upon as an advanced, superior file-system and one of the strong points of the Solaris/OpenSolaris platform while most feel that only recently has Linux been able to catch-up on the file-system front with EXT4 and the still-experimental Btrfs. ZFS is copy-on-write, self-healing with 256-bit checksums, supports compression, online pool growth, scales much better than the UFS file-system commonly used on BSD operating systems, supports snapshots, supports deduplication, and the list goes on for the features of this file-system developed by Sun Microsystems. In this article we are seeing how well the performance of the ZFS file-system under PC-BSD/FreeBSD 8.1 stacks up to UFS (including UFS+J and UFS+S) and on the Linux side with EXT4 and Btrfs.

"The first bits of the Sun ZFS benchmarks were shared yesterday when publishing the ZFS on FreeBSD's new CAM-based ATA infrastructure results (all of these test results in this article are also using CAM-ATA to take advantage of modern Serial ATA drive features). Again, the test system was a Lenovo ThinkPad T61 notebook with an Intel Core 2 Duo T9300 (Penryn) processor, 4GB of system memory, a 100GB Hitachi HTS72201 7200RPM Serial ATA 2.0 hard drive, and a NVIDIA Quadro NVS 140M graphics processor. The ZFS support within FreeBSD had improved greatly with FreeBSD 8.0 and then further matured with the FreeBSD 8.1 kernel."
