Hi,
I got something like this some time ago. When I installed 5.2 (don't
remember the exact level) 64bit on a 64bit AIX 5.1 kernel, things were going
slow and CPU use was very high. Just for curiosity I uninstalled the server and
installed the 32bit version, without changing anything on the OS. To my
surprise, CPU util dropped sharply and everything (backups, expiration) ran
much faster.
This particular server is still runnning the 32bit code today.

Assunto: Slow backups after TSM Server upgrade
Yesterday I upgraded my TSM server to 5.2.6.1 from 5.1.6.3. While the system
was running on AIX 4.3.3 and TSM 5.1.6.3 backups were fairly quick and
typically if I saw a backup running in the morning when I came in it pointed to
a NIC/SWITCH mismatch. After upgrading AIX to 5.2, TSM still 5.1.6.3, the
system seemed the same, and by the way I should mention the system was running
64 bit mode but was NOT running 64 bit TSM code.
When I upgraded TSM yesterday I changed to the 64 bit code thinking things
should be "at least as fast". As I watched backups last night things seemed
quite slow. The database backups seem to have quadrupled in the time it takes
to complete one. This morning I also see 7 backups still running.
So the question is have others seen a drop in performance after upgrading to
5.2 TSM?
Thanks for any insight you can provide,
Thanks,
