I can see in branch 1.1 that CompactSplitThread does load a CompactionThroughputController here [1], and it's possible to set PressureAwareCompactionThroughputController [2] on "hbase.regionserver.throughput.controller" property. PressureAwareCompactionThroughputController defines additional configurations to control, eventually slowing down, compaction throughput.
HStore also considers offpeak hours when creating the compaction request [3]. Offpeak configurations then available would be "hbase.offpeak.end.hour" and "hbase.offpeak.start.hour".
