You have to make sure you have proper indexes in your LDAP database, at
least these:
index objectClass eq
index cn pres,eq,sub
index mail pres,eq,sub
index uid pres,eq,sub
I have 175,000 records in my LDAP db, two slaves get hit by 28
mailservers. The lookups are very fast, and the ldap boxes rarely hit a
load higher than 0.50 .

Do you already have a large number of records in your ldap database?

Hi Catalin,
You can also have a check with your hardware, especially the disk IO. I had
experienced problems such as this before on a production mail server I am
maintaining and found out that the problem was due to a faulty disk array
installed on the server.
Best regards,

Hello
I have the following setup: openldap 2.2.36 qmail-1.03 +
qmail-ldap-1.03-20050401a , courier pop3 + imap (with authlib latest version).
The ldif looks like this : --ou=administrators
--ou=Groups
--ou=Domain1.com
[EMAIL PROTECTED] (this is
a qmail-group for mailing list)
--ou=Domain1.com
[EMAIL PROTECTED] (same for
domain2.com)
--ou=Users
--ou=Domain1.com
--ou=a
[EMAIL PROTECTED]
Etc.
The messages in queue takes too long to be delivered to users Maildir , Iâve
turn on debugging for ldap and qmail does one search for mail address and the
stop (unbind) for 2 sec and the starts all over again for the next mail. I
know that persistent connection is not an option with openldap , but for what I
have read this setup (openldap +qmail-ldap) is one of the fastest and I this
that Iâm doing something wrong . Please give me an advice .
