NT ADSM Server v3.1.2.13
NT Client 3.1.0.6
100mb etherent

I had to do a test restore on a 100gig partition (NT Server), that had a
little over 4 million files on it...
Files are ditributed with about 8 files per dir, and lots of dir's, off of
a
nested Image directory from the root.

Lots and lots of tiny image files...

32 hours for a complete restore...  doing a NQR...  just straight dump from
ADSM to server on one entire filespace.  (Avg ~3gig/hr)

From the same ADSM server I can get 28-30 gig/hr for an exchange restore (2
files)

Is there an issue with tons of itty-bitty files?

I didn't have collocation turned on, but the delay from mounting tapes was
not measurable with the slow speed of the restore.
