Measurement and Analysis of LDAP Performance

The Lightweight Directory Access Protocol (LDAP) is being used for a number of distributed directory applications. In the current context, it is potentially useful for the management of network resources, and the administration of traffic-handling and pricing policies. In this work, we describe a tool to analyze the performance of LDAP under a variety of access patterns. We report measured performance using a LDAP schema proposed for administration of Service Level Specifications in a DiffServ network. We discuss how various system components affect latency and scalability under various access patterns, and investigate mechanisms for improving performance.
