Database Replication - Performance Improvement

You can use SSRM and System Monitor to determine baseline values for the following

key factors in replication performance:



■ Latency The amount of time it takes for a data change to be propagated

between nodes in a replication topology.



■ Throughput The amount of replication activity (measured in commands

delivered over a period of time) a system can sustain over time.



■ Concurrency The number of replication processes that can operate on a system

simultaneously.



■ Duration of synchronization How long it takes a given synchronization to

complete.



■ Resource consumption Hardware and network resources used in replication

processing.
