You can improve shell performance by controlling the use of STEPLIBs.
A STEPLIB is a set of private libraries used to store a new or test version
of an application program, such as a new version of a runtime library.
To improve performance of the z/OS® shell, avoid propagating STEPLIBs
by using one of the following options:
o If you enter the OMVS command either from ISPF or with STEPLIB data sets
allocated,
include the statements in the shell profile. For example:
if [ -z "$STEPLIB" ] &&; tty -s;
then
export STEPLIB=none
exec sh -L
fi
[ Lots more. There's a semicolon in there that mystifies me. I test "$-"
for 'i' to identify interactive shells. Works wonders for me. ]
