There's also DB tuning I suspect, which I'm entirely clueless on.
All of that is going to be tossed out the window. back-mdb fits 4x as many entries as back-bdb/hdb in the same amount of RAM, runs queries 2x as fast, and has no tuning parameters.

Hello Gibson,
Thks for replying. However, my concern is:
In our production system we have 8GB of ram with 100GB hard disk. So till what limit it the Read/Write operation to LDAP goes smoothly. Lets say - 1 row of data is 10K bytes.
Please don't mind - but we are planning for the afterwards approach. (What to do - when LDAP goes slow with this configuration)
For Example - In mysql we could do first level partitioning the tables and afterwards at last resort we could do its sharding.
So, my query is - Can we do anything other than upgrading H/W or OS if the I/O operation to LDAP gets slow?
Thanks and Regards, Gaurav Gugnani

Well today, my query is pretty generic and lot many people working on LDAP would face such an issues. We are using openldap 2.4.26 with BDB as backend. We've installed the setup on linux machine of 64 bit with 4GB ram. Now, currently we have some 10K records in it and its working perfectly fine. Our systems is running under replication - syncrepl. However, in near future we can foresee some million of records to turn up. So, Can any one please advise - What are the different Scaling options available with LDAP? I'm not sure what you mean by scaling options. OpenLDAP scales, and that has been shown numerous times. How well/far it scales depends entirely on your hardware and operating system and the size of the DB in relation to those things. --Quanah -- Quanah Gibson-Mount Sr. Member of Technical Staff Zimbra, Inc A Division of VMware, Inc. -------------------- Zimbra :: the leader in open source messaging and collaboration
