Lars Hofhansl commented on HBASE-12988:
---------------------------------------
Another observation from [~abhishek.chouhan]'s testing was that the majority of
the time is spent at the sink applying the edits. The test was done over high
latency links (~60ms), and this surprised me the most. It's not the network,
it's the time spent on the sink and the fact that the source is not doing _any_
work during that time, since it synchronously waits for the sink to finish.
