I'm not seeing any slowdown against back-null, so it would seem to be
BDB or back-bdb related.
Actually, there's no functional difference in back-bdb between HEAD and
RE23. But I'm definitely seeing a 10% slowdown in HEAD vs RE23 now. Will
have to profile it to see where the difference lies.
Interesting that I'm not seeing the same extremes as you; I'm getting
6600 auths/second on RE23, and 6200/sec on HEAD on my dev machine.
