We are performing a restore that is running real slow.

client:  hpux 11.11, tsm v5.5.0
tsm server:  v5.4.1

The restore operation is about 1000 files totaling about 600gb. The tsm
server is sitting with the session on SendW.    When dsmc is first started
it runs the restore at about 10-15mb/s.  After some time (an hour or so) it
slows to a crawl.  The problem appears to be that dsmc is running an entire
processor flat out at 100%.  In other words, dsmc becomes cpu bound.  We
have killed and restarted it several times and the same pattern occurs.

Here is dsmc cmd we ran:
dsmc restore /oracle/backup/fedwp1/bkup.hpdw1p.200903081920.fedwp1.hot/
/oracle/backup/paul/ -inactive -subdir=yes -replace=no

Any thoughts on what's happening would be appreciated!

Rick
