You never state the size of your database (how many dns), or the disk size 
of your database (du -c -h *.bdb), so there is no way to tell if these 
settings are in any way valid.

I don't see a checkpoint setting for slapd.conf/cn=config, and I don't see 
an idlcachesize setting.

Also, you are definitely not using "dynamic" groups in the OpenLDAP sense 
of the word, although they would probably perform significantly better for 
you.
