> Profiling of ThriftServer here at SU has indicated that the call
> ThriftUtilities.rowResultFromHBase() is quite inefficient. It first calls
> Result.getRowResult() which is inefficient and slow. Instead by
> reimplementing to create the TRowResult (the thrift return type) straight
> from the KeyValue[] array the performance boost is substantial, reducing time
> serializing the results. In my profiling the time spent in scannerGetList()
> went from 1100ms to 108ms on similar test runs.
