>Are there any clever ideas for speeding up restores??

Some possibilities:

Restoral performance                    - Avoid use of the COMPression
option
                                          for backups, as the client will
have
                                          to uncompress every file being
                                          restored!
                                        - Use Collocation...to the extent
that
                                          you can afford it in Backups.
                                        - ADSMv3 Small File Aggregation
helps
                                          speed restorals.
                                        - ADSMv3 "No Query Restore" speeds
                                          restorals by eliminating the
                                          preliminary step of the server
having
                                          to send the full repertoire of
file
                                          objects it has for the client, and
the
                                          need for the client to traverse
the
                                          list if it already knows what
needs to
                                          be restored.
                                        - Maximize your buffer sizes; but
watch
                                          out for performance penalty at
certain
                                          TCPBufsize sizes (q.v.).
                                        - Minimize your MOUNTRetention value
for
                                          the duration of the restoral so as
to
                                          avoid a new tape mount having to
wait
                                          for a lingering tape to be
dismounted
                                          from that drive.
                                        - Consider disabling sync for that
file
                                          system for the duration of the
                                          restoral.
                                        - Minimize other server activity
during
                                          the restoral period.
                                        - Restoral works by reconstructing
the
                                          file system directory structure
first.
                                          The directories for many operating
                                          systems reside in the ADSM
database
                                          itself; but if yours goes to a
storage
                                          pool, make the storage pool disk
(as
                                          via DIRMc).
