Syncer rate only applies to background sync i.e. when one node is not "uptodate" it will bring it back "uptodate" at that rate. If you are talking about creating a file on one node when both are "uptodate" then that is foreground replication and that goes as fast as the stack/IO/bandwidth will allow. If you tried to change that speed it would negatively impact the application speed. You do have the replication on a seperate link right?
