- BlockStream is the super class of WindowedBlockStream which manage blocks
- CodecPerformanceTest is the class which test the performance. Please
change the CodecPerformanceTest.loop to a number bigger than 100 before really
do the performance test. And test the use case one by one as initialize impact
