(85eef1f3)[r...@ss4200 ~]# atacontrol mode ad0 PIO4 current mode = PIO2 (85eef1f3)[r...@ss4200 ~]# atacontrol mode ad0 PIO4 current mode = PIO2 (85eef1f3)[r...@ss4200 ~]# dd if=/dev/ad0 of=/dev/null bs=4096 count=4096 4096+0 records in 4096+0 records out 16777216 bytes transferred in 10.111748 secs (1659181 bytes/sec) Nothing I've tried seems to boost the throughput, hence the desire to use a compressed cached filesystem image.
