You don't mention your version of TSM server or h/w platform and this is
a fairly old APAR but I thought I'd mention it.

APAR IC47731  deals with poor performance on Linux kernel 2.6 on
zSeries.

We started using TSM on Linux back when Redhat 8 was in production. It
has worked well for us except for one thing. Every time we try to update
the OS to anything using a 2.6 kernel (CentOS 4.4 for example) the TSM
server performs terribly under load.

For example, at 10:00pm when about 15 machines start a backup you can
not get an admin console to start for about 5 to 10 minutes. We always
end up going back to RedHat 8 with 2.4.x kernel. From all the testing we
have done it appears that the 2.6.x kernel is the problem.
