The RQM SENDQ flush interval is how often we update the send progress
table. We don't have to do this with every ACK that we receive from the
target because the target is keeping track of the receive progress table
as part of the replicated data apply. The purpose of the progress table
on the source is to minimize the amount of data that we would send to a
given target during recovery of the server - but it is the target which
ensures duplicate detection.

This has nothing to do with how fast we send replicated data to the targets.
