Tuning Directory Server Performance
This chapter describes the tools provided with Red Hat Directory Server to help optimize performance.
It also provides tips to improve the performance of the directory.
15.1. Tuning Server Performance
The server's performance can be managed and improved by limiting the amount of resources the
server uses to process client search requests, which is done by defining four settings:
• The maximum number of entries the server returns to the client in response to a search operation
(size limit attribute).
• The maximum amount of real time (in seconds) for the server to spend performing a search request
(time limit attribute).
• The time (in seconds) during which the server maintains an idle connection before terminating it
(idle timeout attribute).
• The maximum number of file descriptors available to the Directory Server (max number of file
descriptors attribute).
To configure Directory Server to optimize performance, do the following:
1. In the Directory Server Console, select the
Configuration
tab, and then select the topmost entry
in the navigation tree in the left pane.
The tabs that are displayed in the right pane control server-wide configuration attributes.
1. Select the
Performance
tab in the right pane.
The current server performance settings appear.
2. Set the maximum number of entries the server will return to the client in response to a search
operation by entering a new value in the
Size Limit
text box.
To keep from setting a limit, type
-1
in this text box.
3. Enter the maximum amount of real time (in seconds) for the server to spend performing a search
request in the
Time Limit
text box.
To keep from setting a limit, type
-1
in this text box.
4. Enter the time (in seconds) for the server to maintain an idle connection before terminating it in the
Idle Timeout
text box.
To keep from setting a limit, type zero (
0
) in this text box.
5. Set the maximum number of file descriptors available to the Directory Server in the
Max Number
of File Descriptors
text box. For more information on this parameter, see the
Directory Server
Configuration, Command, and File Reference
.
For a better understanding of how these parameters impact the server's search performance, see
Section 10.1, “About Indexes”
