Half an engine? No. It means basically that if you sample the work over
a period of time, that 50% of the time that the work was eligible to be
dispatched it actually was dispatched.

Not even close if you have I/O included in the definition of VELOCITY.
(A viable option since they removed disconnect time as a component for
calculating velocity ~OS/390 2.8, iirc)

Is it possible that NDM needs to be tuned (region size, internal config
parameters, etc) to be able to better handle large files?
Lots of CPU usage for an extended period of time is to me
WLM just gave the CPU to NDM. It's not a problem unless you had other
higher importance workload affected.
Well, I disagree with your "it's not a problem" statement because OP said,
"This caused us to hit our softcap and affected other tasks in the

In theory an application that has low cpu demands can achieve a
relatively high velocity -unless-
Well, I like the resource group solution but I have to wonder how well STCLOW
does normally with a vel = 50 at imp. 4. I might think that this is a never
achieving goal service class from all of what might be in STCLOW, but of course
I could be way wrong too.
I'd resource cap max it, CD,

Compress first.
Then encrypt.
If I recall from my basic computer courses in the mid-1970's.

I agree.
All I meant was if you are going to do both:
Compress
Then encrypt.
I haven't seen value in compression for years.
