For the performance-minded, I wrote an article on OpenLDAP for Linux-Magazin's
Performance and Tuning book, which was just published. You can download the
Table of Contents here:

The article summarizes some of the tuning work we've done from ~2005 to the
current 2.4 release. (Despite the German publisher, I wrote the article in
English.)
