With this TCP settings same server serve NFS requests via 40G Ethernet on
multiply clients with speed via 1G Eth ~ 105/110 MB/sec  write/read.
Of course I'll try to change congestion algorithm, but I don't think that
will help.

Also need to test setup with infniband set from connected mode to datagram
