Sun Java System Directory Server Enterprise Edition 6.3 Deployment Planning Guide

Directory Server and Processors

As a multithreaded process built to work on systems with multiple processors, Directory Server performance scales linearly in most cases as you devote more processors to it. When running Directory Server on a system with many processors, consider using the dsconf command to adjust the server property thread-count, which is the number of threads Directory Server starts to process server operations.

In specific directory deployments, however, adding more processors might not significantly impact performance. When handling demanding performance requirements for searching, indexing, and replication, consider load balancing and directory proxy technologies as part of the solution.
