Phoronix: Running ZFS With CAM-based ATA On FreeBSD 8.1
As was mentioned in last Friday's article, Which Is Faster: Debian Linux or FreeBSD, tests of FreeBSD atop the ZFS file-system (rather than UFS2+S) are currently underway and those results are expected to be published in full later this week as the ZFS disk performance is compared directly to UFS2+S, UFS2+J, and also Ubuntu Linux with the EXT4 and Btrfs file-systems. Today though we have a few ZFS performance numbers to share as we look at the performance of the new CAM-ATA sub-system on FreeBSD.
Here is the only benchmarking test between UFS journaling and softupdates that I could find quickly. Maybe this is something Phoronix should test? After all, most popular Linux filesystems use journaling, so it would be good to know how well it stands up against softupdates.
I just wanted to point out a difference between GNU/Linux and FreeBSD systems. Whereas Linux refers to just the kernel, FreeBSD refers to a fully functional Operating System of which kernel is just a small component. The Desktop Environment (Gnome, KDE, ... ), Xorg, even bash shell are third party applications that can be either installed as binaries or compiled from source with the excellent Ports infrastructure. Therefore, it would be great if the following sentence is corrected to:
The software stack being tested consists of the FreeBSD 8.1-RELEASE x86_64 base system with KDE 4.4.45, X.Org Server 1.7.5, and GCC 4.2.1.
Please note the change: word "kernel" is replaced with "base system with".
