systat's default vmstat display shows you the time spend in disk accesses. Typical figures during the dump-restore run were 1.0 for the dump disk and 0.0 for the restore disk, i.e., the dump disk was saturated and the restore disk was practically idle. Also the number of transfers was a magnitude higher for the dump disk, i.e., a larger number of smaller reads compared to a smaller number of larger writes. So, yeah, the dump(8) side is the bottleneck. -- Christian "naddy" Weisgerber [email protected]
