In which version will that be included? 3.5? And is there any documentation on
performance of journal Geo-Rep vs. old Geo-Rep?

Yes, changelog will be part of 3.5.

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.
