answering myself: I'm impressed.

Today (after some testing) I enabled ~1000 forward-zone statements and configured DoT for upstream.
The systems, handling > 100 mio queries per day, did not collapse in the first minutes and even after some hours
there was *absolute no* performance impact visible in the system monitoring.

unbound seems well designed; thanks!
