RE: Disks are getting hammered ?SMPO0001?

Rob,

I found this doc from an old PMR.

And also, but not well documented, the below settings do not apply to IFS.
"For each library"

Save active wait time:
Object locks . . . . . . . . . . . . 120
Pending record changes . . . . . . . 120
Other pending changes . . . . . . . . 120

The IBM page
(https://www.ibm.com/support/pages/brms-parallel-parallel-versus-multiple-library-parallel-concurrent-saves)
still seems a little unclear.  This is the phrase that I wonder about:

"In cases when saving large amounts of small data, parallel support is not the ideal choice and may negatively impact save performance."

What is large amounts of small data? Millions of PDF documents in an RJS directory?
