Elliott Clark updated HBASE-9775:
---------------------------------

I observed better write performances on the 0.96 than 0.94, by about 20% when
inserting 100m of rows from an empty cluster. There are around 18 regions at
this stage IIRC, so the cluster size should not matter that much when we start
from an empty table. I've inserted around 1b w/o issue on 0.96.

Our performance team independently ran some ycsb tests vs HBase 0.94.6. Here's
the graph that they generated. Blue is 94. Orange is 0.96.
X axis is target throughput
Y axis is actual throughput
