Hi Tom,
Try using PDSE for this the performance can be significantly better than
PDS. Make a copy and run some tests.

Subject: LLA and Cobol copybook library
Hi all,
I have a production Cobol Copybook library that is accessed thousands of
times a day during compiles. It's only updated during one 'promote'
job
in the evening.
I'm looking to improve it's performance by getting LLA to manage the
directory which has over 10,000 members. I update the LLA with the
LIBRARIES(COPYBOOK.LIB) and FREEZE(COPYBOOK.LIB) statements and it
appears to work. I can update a member and both ISPF and batch still see
the before member. So far so good.
My first question, is this a valid/acceptable use of LLA to manage
non-loadlibraries?
a "D LLA" command shows the library as frozen.
However, a "D LLA,STATISTICS" doesn't show any MEMBERS FETCHED or DASD
FETCHES. Peter Relson's module fetch monitor doesn't show access for
the
non loadmodule library. Any suggestions on how to monitor the progress?
Finally, Is there any way to get VLF involved as well?
All the best,
Tom
