Subject [jira] [Commented] (HBASE-14921) Memory optimizations

Eshcar Hillel commented on HBASE-14921:
---------------------------------------

Hi [~anoop.hbase], [~ram_krish], 
Did you use ssd machines for the PE?
So far when running the suggested setting on an hdd machine I get an insufficient memory error
even when running the default memstore, so I suspect this is due to IO bottleneck (flushes
are simply too slow).
Can you share the configuration of the machine you run on?
