The dump image itself is not going to disk. It's being passed in a
pipeline between amrestore and ufsrestore. So while it's skipping files
that are not to be restored, nothing will be happening on the disk.

Probably :-), but nothing pops to mind. I've seen issues of df not
reporting things properly for a while after a change and assumed it was
some kind of buffering going on, maybe waiting on a file system sync
operation, but not du. I think ufsrestore brings back files into their
proper location in the directory tree as temp names and then renames
them, so it's probably not an issue of bring them back at the top level
and then moving them into place.

They have nothing (directly) to do with dump and restore. They fix
a problem with the Solaris hme device driver (hence the "hme" in the
variable being set) by forcing full duplex since it cannot seem to auto
negotiate properly (or you could force it to half duplex -- depends on
what your switch wants). If you don't have an hme interface ("netstat
-in"), the entries won't help. And if you do, you need to be certain
how your switch/hub is configured, etc.
If you're having this problem, almost all network traffic will be
effected. For instance, an ftp (binary mode) of several MBytes should
act pathetic. Be sure to test it both directions as the problem sometimes
only shows up on one side.
