Hello,
the LTO microcode that is supposed to fix a performance
problem with the LOCATE function as I explained below
is known as "PGA3".
It is still not yet available. Last I heard was that it could
be available early next week, date subject to change
of course.
I will let you know when I have more information.

Regards,

Hello John,
I have worked with one customer getting the same
behaviour on restore, even with the 0C1 microcode
applied. Small bursts of files being restored at a time.

We have captured TSM and Atape traces and found
TSM to be waiting for LOCATE commands to complete.
We found this to be an LTO  microcode problem.
A new microcode has been developed and is currently
going through final stages of testing.
