So apparently, you want the ration to be no more than 30:1, otherwise
perfomance degrades substantially.

On a 1M entry database I see no performance difference between using the
default rtxnsize (10000) and setting it to zero. Verified using both head
and RE24.

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.
