Hi i am suffering from slow slapadd for a 100,000 subscriber. It is 27 minutes. this is not what i am expecting .

My test environment and the openLDAP release i have installed symas-openldap-silver-2.4.11.0.sun4u.pkg to a System Configuration: Sun Microsystems sun4v SPARC Enterprise T5220 Memory size: 32640 Megabytes

Is it rational that slapadd took 26 minutes for 100,000 entries(23Kbyte per subscriber i guess) without index.? I think it is so slow.isn't it? What have i done wrong then?Could you please help to reduce this time ? And how can i learn what db_stat exactly mean to me while doing slapadd?
