Tomas, 

This can be normal behaviour. It all depends on which media the files
are stored.
For instance I've done a restore of an 800MB Unix file system which was
scattered over 12 LTO-1 tapes and it took 45 min.

The way to improve performance for these kind of restores is using
colocation.

Met vriendelijke groet, With kind regards,
Richard van Denzel.

Hi *SMers,

I had to restore a subdirectory (2000 files) for a fileserver with a lot
of files
(9.5 million files according to QU OCC). According to the docu it was a
no-query-restore (NQR) so all the work was done at the server.
I know that a NQR can take a lot of time, but I think 4:43 hours is too
much in this case.
Is there a guideline how long such a restore should run? If yes, which
server/OS settings should I tune ti improve the restore?

TSM Server: Windows 2003 SP1, TSM 5.3.2, 1GB memory, BufPoolSize 262144
TSM Client: Windows 2000, TSM 5.3.2

Thanks in advance
Thomas Rupp
