Well, how much RAM do you have on the system?  What is the size of your 
*.bdb files?  To have optimal slapadd -q performance, the size of your BDB 
cache defined in the DB_CONFIG file should be the sum of all your *.bdb 
files.

For example on my database:

du -c -h *.bdb

3.3G    total


cat DB_CONFIG
set_cachesize 4 0 1
set_lg_regionmax 262144
set_lg_bsize 2097152
set_lg_dir /var/log/bdb
set_lk_max_locks 3000
set_lk_max_objects 1500
set_lk_max_lockers 1500
set_flags DB_LOG_AUTOREMOVE
set_tas_spins 1
