public class NullReader

extends Master

NullReader: receiver side of uncoupled null tuple benchmark. In contrast to NullIO, which uses a single client for both reads and writes, the NullWriter/NullReader benchmark uses a pair of simultaneously executing clients: one to exclusively write, the other to exclusively read. The observed maximum throughput tends to be noticeably less than in the single client case, even when each executes on a distinct host. (can you figure out why?)
