You can improve server replication performance by running multiple replicator tasks simultaneously. To do this, set the number of replicators by adding this entry in the NOTES.INI file, where the value is the number of replicators.

All other factors aside, it is recommend that you set the number of replicator tasks equal to the number of spoke servers with which the hub replicates. However, you should not exceed 20 replicators to avoid putting too much load on the server. If the server you intended to replicate is not a hub server, the recommended number of replicators should equal the number of processors on the server.

Note:
You must shut down and restart the server for this setting to take effect.
