| Other than running eDirectory on a fast CPU, using lots of RAM, using fast disk drives in RAID configuration, and so on, there are also a few noteworthy tricks you can perform from a software perspective to enhance eDirectory's performance without spending additional money. Because Novell's LDAP server uses eDirectory as the back-end database, its performance can be affected by eDirectory's (for example, memory management [cache settings], indexes, replica placement, and search limits). Certain portions of eDirectory are already configured to take advantage of the presence of multiple processors in the operating environments. The core directory, security, encryption, and LDAP modules are multiprocessor enabled. The following sections discuss the cache settings and indexes in depth. But first, this chapter takes a brief look at replication latency. |
