 From slapd.conf:

tool-threads 4  # this has varied between 1 and 4

syncprov-checkpoint 1 5  #  we've tried using the default settings,  
very lax settings, etc - never made a difference.

checkpoint		10 1   # checkpointing for Berkeley

And the rest of the Berkeley settings in our DIT suffix area:

database		hdb

idlcachesize		30000

dncachesize 	100000

The version of BDB is as fully-patched as Debian keeps up with it.  We  
(as a company) stay on top of updates, while Debian only tends to fix  
security bugs and pretty much will ignore feature issues and lack- 
luster functionality in their packages.  They do this religiously,  
which is shameful.

Thanks again,

Jeff
