The cpu profiling shows that during PE randomWrite testing, about 1 percent of time is spent in cloneFamily. Reviewing code found that when a cell is DBB backed ByteBuffKeyValueCell (which is default with Netty Rpc), cell.getFamilyArray() will call cloneFamily() and there is again a cloneFamily() in the following line of the code. since this is the critical write path processing, this needs to be optimized.
