Run fio test on 1G ethernet. write block size 128K, read also 128k. WRITE: io=3072.0MB, aggrb=63211KB/s, minb=63211KB/s, maxb=63211KB/s, mint=49765msec, maxt=49765msec READ: io=3072.0MB, aggrb=59690KB/s, minb=59690KB/s, maxb=59690KB/s, mint=52701msec, maxt=52701msec That is write about 63MB/s and read about 60MB/s. If I just run scp to copy a big fie, the throughput is about 85MB/s.
