We have the below WLM settings for TSO users.
This was setup a long time ago, about 15 years I think on an older Mainframe.
         1 service class is defined in this workload.

           * Service Class TSOSRV - TSO 
             Base goal:
             CPU Critical flag: NO

               #  Duration   Imp  Goal description
               -  ---------  -    ----------------------------------------
               1  280        1    85% complete within 00:00:00.400
               2  2000       3    50% complete within 00:00:00.950
               3  24000      3    Execution velocity of 15
               4  320000     5    Execution velocity of 10
               5                  Discretionary

Note that service period 1 has 280 as duration and 2000 as service period 2.
"Duration is the amount of service units that a period should consume
before going on to the next goal."

Since newer Mainframes have higher service units/second. Does this mean that this type of WLM definitions needs to be tuned each time, while moving to a faster Mainframe to exploit the benefits.

Could you please share your thoughts and possibly provide your TSO definition at your shop.

Thank you,
