[OSM-dev] Osmosis Replication Statistics

[Brett Henderson]

I just produced 20070721.osm by applying 20070720-20070721.osc to 
20070720.osm.  It took 43m34s to complete.

It took 3m07s to produce 20070720-20070721.osc so this means that a 
daily planet could be produced in approximately 1 hour with less than 5 
minutes of database activity.  The reality on a production system might 
be slightly different of course.

I'll take another look at the snapshot task.  Based on IRC discussions 
there may be a better way of doing this.
