> I've been tracking down a performance issue in trunk vs cassandra-3.0 branch.
> I think I've found it.  CASSANDRA-6696 changed the default memtable flush default to
1 vs the min of 2 in cassandra-3.0.
> I don't see any technical reason for this and we should add back the min of 2 sstable
flushers per disk.
