A buildworld just >took 22.5 hours! That does sound a bit poor. I presume the system was basically unloaded during the buildworld. Can we see the output of: - vmstat -i - zpool status -v - df -k - mount -v - md5 -t [this will help determine if the problem is lack of CPU] - sysctl vm >I have tested the two system drives independently (currently a zfs >mirror), so it is not likely to be an hdd issue. How did you test them and what were the results? Do you know what revision your /usr/src/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/arc.c is? (Or when/how did you last upgrade your source tree). --=20 Peter Jeremy --7JfCtLOvnd9MIVvH Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.15 (FreeBSD) iEYEARECAAYFAkyXQuMACgkQ/opHv/APuIc68QCfa3kA5EDDS7vDI8acojTrUUqI fVcAnRJDZ5NjluTQmkV4+2ch+NWIFpK1 =sv7v -----END PGP SIGNATURE----- --7JfCtLOvnd9MIVvH--
