Hello all,
I've been Google'ing around and searching the archives, but I haven't quite been able to find an answer, so I wanted to ask the list.
I've been experimenting with OpenLDAP adds to see how quickly we can get data inserted into the DB.
I'm using Ubuntu 10.04, and I've tried both the packaged OpenLDAP 2.4.21 using hdb, and just recently the latest OpenLDAP 2.4.39 using lmdb, both with relatively similar results.
The short version is: to insert 1 million records, it's taking about 8 hours on a machine with 2GB RAM / 3Ghz / SSD, which seems like a long time to me.
The insert method is to use a single big ldiff file like this:
have you read slapd-hdb(5) and slapd-mdb(5) on proper database configuration? a slapadd of 1 mio entries takes about 30 min, depending on hardware and filesystem, I haven't used ldapadd for some time, but it shouldn't take much longer.
