Increase Replication Throughput for Active Standby Pairs

You can increase replication throughput for active standby pairs by configuring parallel replication.

By default, replication is performed with a single thread where the nodes in a replication scheme have one log reader, or transmitter thread, on the source database, and one applier, or receiving thread, on the target database. Parallel replication instantiates multiple threads to transmit updates from the source database to the target database and to apply these updates on the target database. See Configuring Parallel Replication.
