Careful with statements like "foo is faster" unless you can back it up.

I've had trouble scaling to large amounts of traffic using both tinydns
and dnscache on certain OS's and hardware that served huge amounts of
traffic running BIND.

Note that I've found that the same sparc hardware running Linux more
than doubles the performance of both tinydns and dnscache. I'll be
converting a lot of sparc boxes to woody in the near future ;)

Use a script, you don't have to manually enter all the blocks. For
10.0.192.0 - 10.0.255.0:

$ cd /service/dnscache/root/ip
$ for net in `seq 192 1 255` ; do touch 10.0.$net ;done

The OpenBSD people are planning a replacement too, but that's a ways
off.
