> Ref. the following DFSIO output, I was surprised the test throughput was only {{17}}
MB/s, which doesn't make sense for a real cluster. Maybe it's used for other purpose? For
users, it may make more sense to give the throughput 1610 MB/s (1228800/763), calculated by
*Total MBytes processed / Test exec time*.
