   I've been performing additional benchmarks, focussed on replication recently. I was not able to demonstrate a replication performance gain due to e.g. `_changes` performance gains. I was able to demonstrate the opposite however, finding a q=192, 1M doc DB takes ~80% longer to index with the stream limit set to 100.
   
   The stream limit 5 and 10 replication time results were within error of each other for q=192 and 1M docs. I believe this indicates replication's dominant bottleneck is not rexi's streaming performance.
