Of course logging has side effect on performance.  Additionally you
may want to store /var/db to a separate partition, and separate the
journal out with a DB_CONFIG file.

Personally I would suggest that you set it to 32768, and redirect the
log to somewhere else (say, /var/log/slapd.log, etc).

Oh...  I think 0 have the same effect with 32768.  I think it's Ok to have
slapd to log some emergency messages, which helps you to determine what
is happening without big performance pressure :-)
