Performance fixes for new result set
A few small mistakes led to huge callcounts. Additionally,
the warn-on-get behavior which is attempting to warn for
deprecated access in SQLAlchemy 2.0 is very expensive; it's not clear
if its feasible to have this warning or to somehow alter how it
works.
Fixes: #5340
