It was quite easy to configure, and I didn't need to touch it since the initial setup.
I think I just followed the instructions for Debian:
http://wiki.debian.org/DNSSEC#Unbound

I've attached my unbound.conf here if you want to see what it knows. According to the config file
it should use a 4M cache by default.
I didn't measure memory usage, or do any other benchmark to compare it against bind.

[this sentence seems to have been cut off]
