Why are you restarting the AIX box? This is Windows behavior - works after
restart. Did you restarted Windows too?
Have you tested network throughput? Try ftp-ing from Windows to AIX (and
back). What is the transfer rate for file larger than 100-200 MB?
Have you tested B/A client throughput? Try backup&restore of ordinary file
0.5-1GB. You can make new local replica of one big Domino DB outside
<drive>:\lotus\notes\data directory and backup it using GUI.
Is backup going to disk or direct to tape? Is migration starting during
backup to disk?
What is Windows box processor/memory utilization during backup? Is memory
overcommited and paging extensively used?
Is there other high-volume activity on the same partition/disk?
Answers to some of those questions might help you to pinpoint the problem.
If still there is no success report to the list again.

Subject:        TDP performance!!!!!

Hi everybody,

I'm having BIG performance problems using TDP for
Lotus Domino...

I am backing up the mail databases using TDP for Lotus
Domino. My configuration is the following:

-TSM Server 4.2.1 on a AIX 4.3.3
-TSM client 4.2.1 and TDP for Lotus Domino 1.1 on the
-TSM client 4.2.1 and TDP for Lotus Domino 1.1 on the
mail server that is a WIN2000
mail server that is a WIN2000

The company wants to perform a full backup of the mail
database directly on a tape every day. The total size
is of 8GB approximately. First time I did the back up,
it took 1 hour to complete. But since then, I'm
getting a throughput rate as low as 50 Kb/sec !!!
which means that it would need 48 hours at least to
complete the backup.

I verified both the AIX and WIN servers speed
connections and both are of 100 Mb/sec. I then tried a
backup on the tape using the AIX 'tar' command and
got a very good rate. Finally, I restarted the AIX
but I'm still getting this very low rate ...

Can you offer me any advice?

Thx a lot
Sandra
