slapadd newbie
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?
