Hi to all!
I have FreeBSD 8.1 amd64 server, with ufs on first HDD, and I planned to add another 1Tb HDD for backups. I never run FreeBSD on ZFS, that's why I took some computer for test and install FreeBSD 8.1 amd64, ufs on first HDD, and ZFS on second, and run blogbench benchmark:
ad4 - ufs, where FreeBSD installed
ad6 - zfs
What I'm doing after installing FreeBSD:
I know that this is different HDD, but I think that results can't be so different, but I can try put ufs on ad6. And here is my question, why performance on ZFS is so poor, what I'm doing wrong?
