Overview#EDirectory 22.214.171.124 (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.
Then Merge the partition. This is what happens when the Join takes place anyhow and this adds soem control to the process.
