Ive created idea https://ibm-z-hardware-and-operating-systems.ideas.ibm.com/ideas/ZOS-I-4378
z/OSMF enables Java shared library support, (it saves a copy of libraries in memory), but does not exploit it. It is exploited if you restart z/OSMF a second (or more) times within IPL. I reckon it saves half the CPU! See https://colinpaice.blog/2023/08/26/turbo-start-your-java-program-on-z-os-and-save-a-bucket-of-cpu/ The idea says use the existing Java support to harden the shared information across IPLs. This means the first start of z/OSMF will be slow, as today, the next start will use half the CPU. Please vote for it, or add comments to it. I'll look into ZOWE - it doesn't even have shared library support enabled!
