Anastasia Braginsky commented on HBASE-14921:
---------------------------------------------
Yes, 1,280,000 records.
The slowness at the beginning happens anytime with any implementation (at least
when we are working with YCSB).
We believe it is related to the warm-up of the system and the clearing from the
previous experiment.
We usually disregard this spike as it is not typical only to implementation
that is based on CellArrayMap.
