Possible Causes of a Drop in Performance

Make certain that you have not mistaken an active or passive hang for a performance drop. If you are experiencing a performance drop, it could be for one of the following reasons:

• Other processes are affecting CPU or disk access

• Network problems

• High input/ouput rate

• Memory swapping

• Unindexed searches, such as when an index is missing or when a “!” filter is used

• Complex searches, such as searches on static groups, class of service, and roles

• Complex updates, such as to static groups, class of service, and roles

• Sub-optimum hardware

• Sub-optimum system settings, such as fds or keepalive

• Directory Server tuned incorrectly
