I see the differences I've noted with at least 3 different DBs of varying size
now. I've dropped the 300kish one on ada.
With your 300k entry DB and config I see a full subtree search take about
10.4s with rtxnsize = 0, vs 11.7s with rtxnsize = 10000. Measurable certainly,
but not really noticeable.
