That improved performance a lot, similar to what can be seen in the 'distributed world'. Before that, 'getmain at the given address' was implemented to make the parent identical to the child in the beginning.
I know the storage part and its efficiency, but creating an address space is something else, that costs time. > > >- If the DP's are well positioned between the Sysstc (MQ etc.) and the > >low prio other stuff, what exactly do you expect from WLM? > > a) skip the 'I don't look at you for a while' algorithm for *this* workload. We have these spikes, and 30s are too long if there really is an increase in load and "someone else has the high DP due to WBIFN not needing it/being overlooked for that interval." THIS is what CPU Critical prevents, if 'someone else' has a lower IMP than your WBIFN. Maybe you can look at this again.
