!! [EDirectory Synchronization] [EDirectory Performance Tuning]
In [EDirectory 9.1.0.0 (40101.29)] and later  some [EDirectory Background Processes] have been redesigned to cater to large, dynamic environments.

[eDirectory] Support recommend that you set the Background Process Delay Settings to a Hard Limit to 5ms and enable [Asynchronous Outbound Synchronization]. However, if the [CPU] utilization goes high, increase the sleep duration.

[eDirectory] Support reported lab tests were performed on a setup of 10 servers with the following settings: Hard Limit- 0ms, [Asynchronous Outbound Synchronization] - enabled, and Async Dispatcher Thread Delay - 0ms. The tests have shown that [replication] is 7 times faster than with the default settings. During this test, no other client operations were performed.

%%warning
Enabling [{$pagename}] may lead to increased [CPU] and I/O utilization at the receiving server. To avoid this, you can set a __delay__ in sending the packets by specifying a delay interval in Async Dispatcher [NDS Thread] Delay. You can set this delay interval between 0 to 999 milliseconds. The default value is zero milliseconds.

%%information
To reap the best benefits of the performance of your systems with these scalability enhancements, you must be on [EDirectory 9.1.0.0 (40101.29)] or later on all servers. Even if there are some older versions in the replica ring, there is improvement in performance.

NOTE:

!! Removing a [Partition]
When partitioning notes for large trees and removing a partition, you can speed things up by making all replicas R/O except Master.

Then Merge the partition. This is what happens when the Join takes place anyhow and this adds soem control to the process.
