Performance of the new journal based geo-rep should be better than old geo-rep due to these improvements: - Easier identification of changes by querying changelog - Parallel geo-replication which utilizes multiple nodes on the master & slave for data replication. The earlier implementation had a single channel through which replication would happen. Running performance tests during the community test day for 3.5 might be helpful in determining the performance gain with parallel changelog based geo-replication. -Vijay
