| `desiredLatency`
| Integer
| Default: 50.
| Specifies the amount of time in milliseconds within which a high-priority replication's currently remaining changes should be reduced in number to zero, by ongoing transmission of the changes from source to target bucket.
If Couchbase Server estimates that the time required is greater than that specified by `desiredLatency`, the replication is considered to be backlogged: XDCR therefore attempts to communicate with the Data Service, to establish a higher DCP priority for the replication, and thereby ensure swifter transmission of data.

This setting applies only to high-priority replications, or to medium-priority replications that achieve high-priority status (see xref:learn:clusters-and-availability/xdcr-overview.adoc#xdcr-priority[XDCR Priority]).
The default value is 50.
The lower the value, the higher (potentially) the transmission rate, and the greater the load on the target cluster.

| `docBatchSizeKb`
