Hi all,

last week we upgraded our TSM 6.3.3.0 servers on windows to 7.1.1.100. Since 
then we notice that:

- label libvol takes about 3 minutes per volume
- some tape mounts on one server take well over 10 minutes to complete

This is on win2k8r2 with all the latest patches, and a IBM ProtecTier VTL. With 
6.3.3 label libvol would take about 2 seconds per volume, on the same OS, same 
IBMTAPE driver, and same VTL level. There are 0 errors on the SAN. And the IBM 
Tape device driver is fairly recent, if not at the latest level.

Has anyone seen this before? And if so, what was the solution?
