This seems interesting to me, since my connection code is largely from HEAD. In 2.3, I get 15,000+ auths/second on my 64 bit test systems, but with straight HEAD code, I only get 5,000 auths/second.
In both cases, the lightweight dispatcher code is enabled. Any thoughts on what else may be affecting HEAD? The configuration is very simple, just a small 250k bdb database.
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.
