Thanks. I will check in to see if that is an option. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Ron Burr Sent: Monday, May 2, 2016 7:34 AM To: [email protected] Subject: Re: PDS I/O Performance Improvement
I haven't seen it mentioned, so thought I would bring up the issue of "user data" in the PDS member entries. We weren't told whether the PDS did or did not support 'user data' for its members, but if the PDS is being maintained using ISPF with STATS ON (the default), then a performance hit in the retrieval of a given member will be the result. Each directory block can contain roughly 3 times as many member names without 'user data', than one maintained with ISPF STATS ON. In a PDS with 180,000 members, that can make a huge difference.
