I've done numerous tests with dump and different buffer sizes etc, but the maximum speed I can read from disk is approximately 14MB/s (measured by iostat).
cpio / tar etc can read from disk at over 30MB/s .. Dump seems to spawn children (presumably for better IO) - is it possible to tweak the number of children for better IO performance. I can write to my tape unit at a sustained 25MB/s (AIT-3 on an LVD interface), so I'm wasting tape and time.
