In normal hours, the max throughput is tuned between
"hbase.hstore.compaction.throughput.lower.bound" and
"hbase.hstore.compaction.throughput.higher.bound", using the formula "lower +
(higer - lower) * compactionPressure", where compactionPressure is in range [0.0, 1.0]

"hbase.hstore.flush.throughput.upper.bound", using the formula "lower +
(upper - lower) * flushPressure", where flushPressure is in range [0.0, 1.0)
