Your lock/locker/lock object settings look fine.

Your BDB db cachesize is 256MB then, which is more than sufficient for your 
136MB database.

However, you missed my point about the "cachesize" setting in slapd.conf 
(NOT DB_CONFIG).  You should have a cachesize setting in slapd.conf (of 
probably 45000 and a similar idlcachesize setting in slapd.conf as well).

Unlikely.  How exactly are you measuring performance?
