dump reads more than restore writes?

Quite possibly, esp. if the source disk is nowhere near full and/or
most of the files being handled are small.  dump reads every inode
on the disk, including those which are unallocated, and probably
reads entire data blocks -- or even entire FS blocks -- even when
only part of the block contains useful data.  Restore writes only
what it has to.
