[Fedora-directory-users] LDAP Accounts for large website

Thu Dec 13 20:04:51 UTC 2007

Here are the specs on the server: 
2 x 2.0Ghz Intel Dual Core Xeon 
4 x 1Gb Registered ECC RAM 
2 x 74Gb Western Digital Raptors 
Given that, the hardware issue should be more than sufficient. 
Network connections are Gigabit full duplex throughout our cage network. 

How would we go about indexing the attributes? 

Me and another sys admin have a distinct feeling that it is an issue with the query, but they are going to point blame at us, so we want to make sure that we are golden before saying it's the code.

Performance is often impacted greatly by 

1) Memory on the LDAP server. Make sure you can store as much of your directory data store in RAM for fast access 
2) Indexing. Make sure attributes that you search on freqently are indexed. Also, limit what fields you search on to avoid having a heavy indexing tax. 
3) Make sure your network connections are stable, and your not connecting on a 100MB half duplex connection while your network equiptment is expecting a full duplex connection. 

Once you have auditing those situations, please check your performance again.

50k accounts is not that much, and a 2GHz Pentium Class or 1.5GHz Core 2 system with 1GB-2GB of RAM should perform okay.

I was wondering if anyone here has ever used LDAP for a website, that will potentially have millions of LDAP accounts. 
If so, are you experiencing slow query responses or other issues? 
If you were experiencing slow query responses, and were able to rectify the issue, how did you do this? 
We are currently using FDS for our main website for customer accounts. We currently have over 52,000 accounts in LDAP and have only been using this for 3 months. We are now experiencing extreme slow down in query response when getting customer data into and out of the LDAP servers. 
Any help would be greatly appreciated.
