XCF Performance WSC White Paper

(Originally posted 2007-05-16.)

I’m reminded of this white paper on XCF Performance from Joan Kelley and Kathy Walsh. It’s a good read and has been recently updated.

It does also remind me that there are “D XCF” subcommands that give information that isn’t in the RMF data (SMF 74 Subtype 2). We process these records in our consulting and I’m getting considerably more familiar the underlying data.

(I also had a situation recently where large messages went through the coupling facility, whereas the standard messages had no opportunity to do so.)
