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.
Followup:
No, it didn't fix the speed problem. When using the ldbm backend, the
machine sits at load around 0.1 and 2% or 3% cpu usage. I switch to bdb
backend and my load jumps to 14 or so, searches take seconds to complete
(of course slows down as the load gets higher). At that point, the
acceptance of new incoming connects gets degraded enough that it drops
out of the load balancer until OpenLDAP catches up on things. In short,
I wasn't able to get it to work. I had to go back to ldbm. I'll keep
hacking away at it.
