I'll buy that: what was the application that did the restore?  Was it
file-by-file or was there some sort of image restore involved?

FYI,

I recently restored 249 GB - 298,801 files (20,318 folders) in 1 hour 41
minutes on a Windows 2003 R2 SP1 server.

==> 177,505 files per hour

(This restore actually wasn't done with TSM but it does show a higher #
of files created per hour than below.)

I have done some testing on restore times and have concluded that a
Microsoft Windows box can create between 50-60,000 files per hour.  No
faster.  So I would conclude that your restore time is optimum.  Based
on my experience, obviously.  If others have more up-to-date information
about file create speeds, please share.  But I am confident that you
have done what you can do on this particular restore.

For grins, create a very large file and backup and restore that file to
see what you get.  What I have found for small numbers of  large files,
backup time will equal restore time.
