It was long before 2002 that I was using LLA to improve TSO / ISPF response times. I have a sample CSVLLAxx member in my personal library from 1995 that was using this technique and found reference to doing the same thing in 1994 in a weekly status report from a former client of mine. Along with removing STEPLIBs from logon PROCs, this was S.O.P. for me to improve TSO / ISPF performance.
