If you're looking to boost input speed, try altering the BDB environment
with something like:

set_cachesize 0 500000000 2
set_flags DB_TXN_NOSYNC

in /var/lib/ldap/DB_CONFIG (or wherever your BDB files are). You can bump up
the cache size even more if you've got more RAM.

This will cut disk I/O and speed up the import *dramatically,* but be
prepared to have BDB write out a *lot* of transaction logs, especially for
6.5M entries. Hope your disk is big. :-)
