Hello all: According to the docs, the geo replication is asynchronous. I assume that means it is not real-time. How much of a delay should I expect for files to be replicated across a network?

Hello: Let me ask this question a different way: Can someone please give me an overview of the geo-replication architecture. Is there some process that is called every x minutes?
