Re: slapd cause too much load

Hi Al
thought about extending real memory, using a different pattern of indexing your ldap-db?

Hello openldap-software,

 I'm running OpenLDAP 2.1.22 on FreeBSD 4.8R-p10. The problem is
 slapd is consuming 30-50% of CPU, causing sometimes problems with
 authentication services (i.e. for cyrus-imapd). How do i know if
 there is some tuning needed to slapd, i mean, if there is some
 log-parsers or something? For now cyrus doing plaintext auth with
 saslauthd, but i have plans for more secure MD5 auth with LDAP, and
 i think that load will be even greater then, so i need to do
 something now, while i have not too much load on slapd machine.

 There is postfix&cyrus on the slapd machine and squid&radius on
 the other machine using LDAP database for authentication. I'm
 thinking about to run slave slapd on squid&radius machine to split
 load, but i need to know that slave slapd is the only way. I'm
 wondering that maybe i can tune slapd or reduce load somehow other

Postfix using LDAP for local recipients map, and cyrus, squid, and
radius for authentication purposes.
Machine is:
