Under normal load tinydns' performance is more than adequate, but under DDoS attack the fact that it's a single process is a definite limitation when it's running on a multi-core machine. By default tinydns opens its database file for every request which can lead to I/O errors under very heavy load. I've patched it (http://tinydns.org/one-second.patch http://tinydns.org/one-second.patch) to only open the database every second, but with my Go rewrite I can easily keep the database in memory and reload it when the disk file changes.
