Hello people,
one of my customers is running into the following problem;
With TSM server 3.7 on NT 4 sp6a, and TSM client 3.7 on NT4 sp6a, restore
is really slow. Checking all normal parameters in both server and client
.opt files does not seem to help. My suspiscion is then turned to network
issues, but according to the customer, they do not have any network
problems.

When I restore using the client GUI, and watch the status indicator, when a
file reaches 100%, it waits for a long time (bigger file - longer time)
before it continues with the next, I have also watched
performance/utililzation of CPU, memory and network traffic, on both client
and server while doing this, and none of these indicates that something is
unusual. Both CPU and mem is low, network is maxed, but drops when a file
is done. The result is a throughput somewhere around 950MB per hour. Not
very impressing.

Is this likely to be a TSM problem, or in other words - where should I go
from here?

Any suggestions will be helpful!
