Hi All,

     We recently upgraded the TSM clients on our cryus imap servers from
5.3.0.12 to 5.4.1.2 (and then 5.4.1.5), and since that upgrade, we have
seen the backups of about 4.5million files in each of our 12 spools go
from about 2.5 hours to approx. 4 days (had we let it run to completion).

Anyone else seeing issues with 5.4.x on Solaris clients with millions of
files?

Other vitals:
 Server: 5.4.1.2 on AIX
 Network: GB

 Client OS Solaris 2.9
  Filesystems are VxFS on an Hitachi 9960.

We have opened a PMR with IBM, and they want to run some traces, but we
have since reverted back to 5.3.0.12, and our 2.5hr backups.

We need to run 5.4 to stay supported, and a minimum of 5.4.1.2 for the
fix for the security issues in dsmcad, which we use for email restores on
these systems.

Thanks in advance for any insights anyone can provide.
