Linked from linuxtoday.com, I found an interesting article posted on FlexTk regarding NAS Performance Comparisons between Linux, Windows and OpenSolaris. The results are very interesting. Under each category, comparisons are drawn between:

• Red Hat Enterprise Linux 5.3 (64-bit)
• Ubuntu Server 9.04 (64-bit)
• OpenSolaris 2009.06 (64-bit)
• Windows Server 2003 (64-bit)
• Windows Server 2008 (64-bit)
• Windows Storage Server 2008 (64-bit)

I assume that each operating system is utilizing the default file systems with default settings for that specific release. Red Hat and Ubuntu should be using Ext3-fs, Windows obviously uses NTFS while OpenSolaris is built on top of ZFS. The CIFS/NFS exported share(s) in turn are running on top of these defaulted file systems. Either way, with average overall performance, OpenSolaris seemed to really shine. It also did well in some of the other categories which made sense when knowing the design of the ZFS file system.
