So you say that master/slave replication takes up to 20 seconds but it takes 8-10 minutes just to copy the entire index?
Solr is _already_ speeding up your copy enormously by just copying changed segments. There's nothing magic you can do to make it faster. And if your master happens to merge many segments into a large one your replication will take up to the time it takes to copy your entire index (8-10 minutes). Going to SolrCloud would eliminate that kind of lag at the expense of indexing on every node. Otherwise it's the best you can do.
