Ah, that's good to know.  I upgraded an old 2.1.30 production server to
2.3.21 with bdb 4.3 and the load went through the roof, searches were
blindingly slow, etc.  I'm rolling back to 2.2.30 right now with db 4.2.
We'll see if that fixes my speed problem.

Speaking of speed problem, I'm compiling db and openldap on a PIII 700.
I have a speed problem.  30 minutes to build it.  Heh.
