I recently converted my system from Linux to FreeBSD. I backed up all my Linux filesystems to DAT using tar. The backups took about 3 hours. After changing to FreeBSD, I read the tape archives back to disk. However, it took nearly 2 days to read the tape. The dd command seems to indicate to me that I am transfering data at around 15k/sec. This seems horribly slow. My configuration is: Tekram DC-390U SCSI controller (ncr0 controller in kernel) Aiwa GD-8000 DDS-2 DAT drive (kernel indicates 10 MB/s transfers) Any suggestions for improved performance?
