Hello, Mark. You wrote 9 июля 2013 г., 20:41:31: MS> What can you tell us about the system tunings. Can you post a copy of your I need to note, that system as tuned for (a) maximum local read/write speed and (b) maximum TCP throughput in local network, as seen by "iperf".
Results of these separate tunings could be seen in very first message in
this thread (280MiB/s sustained local read from FS and 820Mbit/s of TCP
throughput to client in question).
