In a nutshell: use PDSE, not PDS and that's all.
We can mention VLF, LLA, DLF, Hiperbatch, BLSR and maybe some ISV
products, but IMHO none of them could help in your scenario.
Why PDSE
Better directory search
Caching (that's why it's broken when shared outside of sysplex boundaries)

I am sure I know the answer. But in case something was introduced in the last
few years, is there a facility that would cache
in memory a library (PDS/PDSE), directory and members? This would be a library
NOT covered by the COFVLFxx Classes.
Looking at DASD statistics for our BMC CTx product libraries, I see that the
CTx parmlib dataset gets hundreds of thousands of
batch job hits, with millions of I/O to the library. The DASD controller cache
hit percent is 97. But the best and fastest I/O is no
I/O.
Did Batch LSR support libraries and does anyone still use BLSR?
