LLA is Linklist Look-Aside. It is an in-memory cache of frequently used
modules and it is used to avoid some of the I/O and initialization
processing for such requests (another thing Peter looks after)
LLA *was* the LNKLST Look-Aside (once upon a time). It was generalized
decades ago to be the "Library Look-Aside" and works for all kinds of
PDS libraries -- not just those housing load modules. LLA does not cache
the library members themselves, but rather the directory (BLDL) entries
that point to them. For "frozen" libraries (including LNKLST), the
Virtual Lookaside Facility (VLF), if properly configured via COFVLFxx,
will (among other things) cache library members that LLA says are
eligible for such treatment.
