Tuning System Settings
Chapter 5 Tuning the Operating System 105
Inactive Connections
Some systems allow you to configure the interval between transmission of
keepalive packets. This setting can determine how long a TCP connection is
maintained while inactive and potentially disconnected. When set too high, the
keepalive interval may cause the system to use unnecessary resources keeping
connections alive for clients that have become disconnected. For most
deployments, setting this parameter to a value of 600 seconds (600,000 milliseconds
= 10 minutes) allows more concurrent connections to Directory Server.

/usr/sbin/directoryserver idsktune (packaged version) or idsktune (no
packages).
Incoming Connections
Some systems allow you to configure how long a system waits for an incoming
connection notsending acknowledgements. When settoo high,this can cause long
delays in detecting connection failure. For intranet deployments on fast and
reliable networks, setting this parameter to a value of 600 seconds (600,000
milliseconds = 10 minutes) may improve performance.

Outgoing Connections
Some systems allow you to configure how long a system waits for an outgoing
connection to be established. When set too high, establishing outgoing connections
to destination servers such as replicas not responding quickly can cause long
delays. For intranet deployments on fast and reliable networks, setting this
parameter to a value of 10 seconds may improve performance.
