A couple of notes and queries re.

RRL: I don't think this is a good idea on recursive servers; at the very
least it is difficult to tune appropriately for recursive servers.
Also, RRL is available as a build-time option in 9.9.4 and later, and by
default in all builds of 9.10 and later.

The max-cache-size 32 bit limit was fixed in 9.9.3.

Do you have any guidelines on --with-tuning=large in 9.10, or related
configuration knobs for 9.9?

5 or 6. Slight or moderate. Showers in northwest. Good.
