Phil,
Did you check the general network speed between the client and the server
( e.g. ftp put and get a large file ). If you are in a switched 100 mb
network
sometimes ( i saw it on our Compaq and RS6000 servers ) the autonegotiate
port speed / mode does not work correct. We set all components (
server/client/switch-ports) manually  to 100 mb full duplex and this solved
the problem.

just a hint but maybe it  helps

Subject:  Slow NT Restore


Hi

We are trying to restore the C drive on a NT server 4.0 Service Pack 5. We
have TCPIP 100 mb full duplex.  The client is 3.1.0.8 and the server is
3.1.2.90 on AIX 4.3.2.

We are observing very slow restore times.  There is no waiting for tape
mounts but when I query sessions wait times of some seconds are observed,
almost as if it restores one file then goes off to do something else.

So far it has taken 20 hours to restore 850mb.  All directories are held on
disk and they have been restored.

Anyone got any ideas on how to speed this up, by a factor of 10 or so.

Regards

Phil Stockton
