类 ReedSolomonBenchmark

java.lang.Object

com.hjcenry.fec.ReedSolomonBenchmark

public class ReedSolomonBenchmark
extends Object

Benchmark of Reed-Solomon encoding. Counts the number of bytes of input data that can be processed per second. The set of data the test runs over is twice as big as the L3 cache in a Xeon processor, so it should simulate the case where data has been read in from a socket.
