While each cpu in the 504 is slower than a 701 cpu, running 4 batch jobs at
the same time should reduce run time because each batch job expect reduced wait
because there is reduced competition for the CPU. However, you could be correct
if the 4 batch jobs are experiencing heavy I/O wait.
Every address space has multiple TCB. Only TCBs that are not in a wait
(dispatchable) are eligible to run on separate CPUs. You are correct but all
TCBs in a wait are not eligible to run.

I'm thinking it could be as simple as say, going from a 701 to a 504.
The overall MIPS are bumped up, multi-task address spaces
I'm pretty sure that each TCP of a task can run on a separate CPU.

I am trying to help the python ibmdb team help me solve an S0C4 abend issue

I've never looked at IXGLOGR address space but my guess is that IXGLOGR would

from IBM documentation (z/OS 2.4):

On the other hand, in System Rexx configuration member AXRxx, you have the
parameter MAXWORKERTASKS, whose maximum value is 32.
I believe that it's because a single id is easier to audit. Apparently easy
audits are more important than actual security.

I think it’s not having multiple ID inasmuch as the implied sharing. Oddly
