Hi

The short question:
What is the most effective (fast) way to move data between different storage keys ?

The longer story:
We have an FSS application ( running in JESKEY) which starts different user programs, and exchange the data with the user programs
(via SVC screening  and access method routine changes )
For a long time, the user application was also run in JESKEY..
Since a year, the user applications started to use the shared memory (over Uss) and we found, it is necesary to run in key 8 to use shared memory So now the user applications are running in key8 , and we are using PC routines to go into JESKEY, and MVCSK and MVCDK to move data.
It is working so, but the CPU consumption is much higher as it was before.

How can I solve this ?
Can I  use here  KEY=NINE  (Storage Protection Override) .
