(current standard libc_r slapd)...

If you use kse you should have :

        libc_r.so.5 => /usr/lib/libkse.so.1 (0x284c4000)

OK. So to get the threading working for Openldap in FreeBSD 5.2.1 I need to do a Make world with "WITH_LIBMAP=yes" and use the "Kernel Scheduled Entities". Is that correct?

On FreeBSD 5.2.1 default threads are same as on 4.x branch... Excepted if you add made a make world with "WITH_LIBMAP=yes" in /etc/make.conf....

Then if you use kse you'll get a system that can use all your processors...

If not... your openldap process will only use on CPU at time what ever number of CPU you have.

I am trying to verify that my server running "FreeBSD 5.2.1-RELEASE" is actually using multiple threads for Openldap. The system has dual p4's with hyper threading. I've been searching the web and archive with no luck. Any insight would be appreciated.

When I do ps -axH all I get back is one process:
73670 ?? SLs 0:04.19 /usr/local/libexec/slapd -h ldapi://%2fvar%2frun%2fopenldap%2fldapi/ ldap://0.0.0.0/ -u ldap -g ldap


Top -H is similar and appears to only be using one of the processors at a time
70022 ldap 96 0 182M 62380K select 3 1:09 0.00% 0.00% slapd


The FreeBSD port seems to be passing "--with-threads=posix" to configure so I assume it's compiled with threads

Thanks, James Saint-Rossy.
