Hi,

Just an update to this. I have solved my slow address books by indexing the ldap correctly.

I am still having issues with processes and threads though!

I have upped the Threads to 200 and the concurrency to 175.

Threads/Processes just don't seem to die or be re-used!

I have had the server on for about an hour, and I now have 104 threads and only 89 connections.
