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
