Lars Hofhansl commented on HBASE-12988:
---------------------------------------

[~stack], this is the issue I was mentioning. Check out the number from June 1st above (that
was a test with maximum parallelism - not correct, but shows the potential), 3 or 5 way I
think.

The later number are for something that works, namely for parallelizing across regions.
