I recently ran some tests on Ubuntu Hardy Server (Linux) comparing JFS, XFS, and ZFS+FUSE. It was all 32-bit and on old hardware, plus I only used bonnie++, so the numbers are really only useful for my hardware. What parameters were used to create the XFS partition in these tests? And, what options were used to mount the file system? Was the kernel 32-bit or 64-bit? Given what I've seen with some of the XFS options (like lazy-count), I am wondering about the options used in these tests. Thanks, Greg
