I don't think so. It's *very* unlikely a driver can mess up linear speed - it's far more easier to mess up random IO. I don't know why it's so (it might be cause by FreeBSD's tiny MAXPHYS), but it's probably not the driver's fault. I've seen this behaviour with other controllers (including plain SATA). >> ZFS was very good, but not so much when compared to Linux file systems= , >=20 > ZFS in your benchmart is similar to UFS. Look at the read speed. --------------enig9AAEFED6A71A3BDBA438E12E Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkk8cPMACgkQldnAQVacBchj6wCfU4dw15e1HI7nTXumjbX42c55 H/sAoMJ8ezO7bYayVEiC8/BVvAd2TGMY =bwb1 -----END PGP SIGNATURE----- --------------enig9AAEFED6A71A3BDBA438E12E--
