I've been using these techniques since 1996, and they still work more than
10 years later.
I've been using them for a lot longer than that.
The performance gain made sense then, and it makes sense now.
Does it with sub-5ms response?
After all, I'm sure you are one of the supporters of the

Ok. Thanks. It seemed reasonable to me.
Are those rules reasonable? I don't assume that, having observed the

You can also choose very selectively whether particular LPARs participate
in particular Sysplex-related services.
For example, let's suppose you have 4 LPARs named (not so creatively)
LPARA, LPARB, LPARC, and LPARD. And let's suppose that those 4 LPARs are
sharing one common Coupling Facility
Ted,

Yes. I usually figure out the saving with 0.35 to 1.5ms response time in
SIMPLEX and 0.75 to 3ms response time in DUPLEX with Synchronous remote
copy. Anything else is usually
