I hate to mention other products on a TSM list but since you asked...
It was Microsoft's DPM 2006 - Administrator recovery - this is a file
level restore.
I think a TSM restore from disk would get similar results - I'll have to
try sometime to compare.

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.
