Document Locking - Server Load

When enabling document locking on a database that is replicated to multiple servers that are connected via a WAN (2Mb dedicated links) what kind of load/network traffic can I expect to be put across the links?

Your going to have consider replication frequency and the amount of the data that will be put on the wire. However if you have a 6.0x environment definitely enable encyrption on both sides, as we’ve seen at least a 10% reduction in on bandwith utilization. Our test scenario with a a mail work load…

So does the Notes server pass the locks around as part of replication, or is it done on the fly as the document is locked?

If it is done on the fly what kind of load does this place on the network?
