What I want to do is to do operations in OpenLDAP server serially, not concurrency in the server. If the back database is configured to load all data in memory, then overhead of executing a operation is approximately equal the overhead of lock relevant overhead in database. So if requests are serially handled in openldap server, the lock subsystem can be remove from backend database.

I just want to compare difference on performance under these two strategy.

Although I use ./configure --without-threads, there are still two work threads,(info thread in gdb: there are two pthread_cond_wait records.)

Would you give me some suggestion to reach the goal, serially handle the received requests in openldap server?

Thanks a lot!

2007/2/14, Pierangelo Masarati openldap-its@openldap.org:

Slapd by design needs at least 2 threads to work. That code is there exactly to avoid silly configurations with less than 2 threads. You're free to modify it, but then you shouldn't complain. Otherwise, if you don't want slapd to use threads you can compile it --without-threads (not --without--threads like you typed).

If you could tell us what your real problem is with threads, maybe we wouldn't both waste time in this rather pointless issue.

p.
