Benchmarks on LDAP directories

This document summarizes the results of benchmarks that compare the performance of 10 different LDAP directory services when loading and querying a directory containing 10 million records. Key findings include: - OpenLDAP showed the fastest load times, while ApacheDS was the slowest, taking over 11 hours to load the directory. - For read operations, OpenLDAP and a proprietary product labeled "A Nonny Mousse #2" achieved the highest searches per second, while ApacheDS again had the lowest performance. - OpenLDAP also performed well for write and authorization operations, often ranking in the top three products. - Mixing read and write loads significantly reduced performance for most products compared to isolated reads or writes.
