Tuning Server Performance

You can manage your server’s performance by limiting the amount of resources
the server uses to proces client search requests. You can define:

•

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) you want 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)
