slapd.conf cachesize only for ldbm?

[Micah Anderson <micah@riseup.net>]

I see in the slapd.conf documention the following:

cachesize <integer>
    Specify the size in entries of the in-memory cache maintained by
the LDBM backend database instance. The default is 1000 entries.

Is this true, that this parameter only affects LDBM backends? If I am
running sleepcat BDB does this do nothing for me (or against me)?

Thanks,
micah
