LDAP, bdb, don't want log files for replication

[ST21@ineo.com]

Hi,

I need a very very fast LDAP server.
I actually use OpenLDAP with bdb, and I notice that most of the time is
taken to write logs for recovery/replication (file log.000000XXXXX).
I don't need this files, and I searched on the web to tune bdb with no
success. I had only found option about cache size, but it's not sufficient.
How can I run an OpenLdap server without generating this files ?

Thanks in avance,
