is a very large local-data list a problem?

Memory-wise, I found that just using local-data with the implied
transparent local-zone was best. With a ~12k hosts list:

# local-data: "ads.com A 127.0.0.1"
$ ps aux| grep unbound
unbound 32557 1.5 0.2  58316 15964 ? Ss 11:27 0:00 /usr/sbin/unbound -d

# local-zone: "ads.com" static
$ ps aux| grep unbound
unbound 32139 0.5 0.7 152840 63352 ? Ss 11:21 0:00 /usr/sbin/unbound -d

# local-zone: "ads.com" refuse
$ ps aux| grep unbound
unbound 32247 2.3 0.7 152840 63432 ? Ss 11:22 0:00 /usr/sbin/unbound -d


Setting a local-data with only the A record will return an empty AAAA.

HTH,
