+Reading, understanding and experimenting using the instructions and information
+in the following sections, will enable you to fully understand how to tailor 
+your directory server to your specific requirements.
+
+Various factors can play a part in how your directory performs on your chosen 
+hardware and environment. We will attempt to discuss these here.
+
+It should be noted that the following information has been collected over time
+from our community based FAQ. So obviously the benefit of this real world experience
+and advice should be of great value to the reader.

+
+H2: Performance Factors
+
