This server is to be going into production soon, so I'm not in the best position to try things. I've however tried disabling prefetch and ZIL. This helped ZFS pass bonnie++, but it deadlocked later on a repeated make -j 4 buildworld. top shows: CPU: 0.0% user, 0.0% nice, 0.0% system, 0.0% interrupt, 100% idle Mem: 194M Active, 32M Inact, 1844M Wired, 48M Cache, 523M Buf, 5799M Free 19285 root 1 76 0 13060K 8876K zfs 2 0:00 0.00% cc1 19141 root 1 76 0 13060K 8876K tx->tx 1 0:00 0.00% cc1 19745 root 1 76 0 13052K 9116K tx->tx 1 0:00 0.00% cc1 1154 root 1 44 0 6896K 980K tx->tx 0 0:00 0.00% syslogd 2136 root 1 44 0 5808K 812K zio->i 2 0:00 0.00% newsyslog etc. This, apart from anything else, may indicate that disabling the features only masks the problems with ZFS, but doesn't eliminate them completely.
