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:

### snip ###

dn: cn=newtest0,ou=customer,dc=test,dc=com

objectclass: inetOrgPerson

userPassword: 90sac90sudasdjcao0sdjtest

telephoneNumber: 61400000000

sn: none

dn: cn=newtest1,ou=customer,dc=test,dc=com

objectclass: inetOrgPerson

userPassword: 90sac90sudasdjcao0sdjtest

telephoneNumber: 61400000000

sn: none

### snip ###

Then add it with ldapadd:

ldapadd -x -D cn=admin,dc=test,dc=com -w test -f ./test

My configuration (for mdb in this instance) used with 2.4.39 is this:

### config ###

include /usr/local/etc/openldap/schema/core.schema

include /usr/local/etc/openldap/schema/cosine.schema

include /usr/local/etc/openldap/schema/inetorgperson.schema

database mdb

directory /usr/local/var/openldap-data

suffix "dc=test,dc=com"

rootdn "cn=admin,dc=test,dc=com"

rootpw test

maxsize 1980732000

#Indexes

index cn,telephoneNumber eq

index objectClass eq

### config ###

Any ideas or things I could try?

Thank you!

Andrew
