Processor requirements

To improve the directory server performance, you must ensure that the LDAP operations use the processor time efficiently.

You must consider the following guidelines to ensure that the processor is used at its optimum level:

• The required data is available in the caches results in low disk accesses. Accessing data from memory is faster than accessing from disk. If data is accessed from memory, it decreases the time that the processor must wait for input/output to occur.
• Enable simultaneous multithreading (SMT) on systems with hyper-threading capabilities. It increases the processing capability and the application throughput. For more information, see Simultaneous multithreading.
• Systems with fewer processors but greater processor frequency is more efficient than systems with more processors but lower processor frequency. For example, a system with two processors with 1200-MHz speed is faster than a system with four processors with 600-MHz speed.
