(In reply to Tom Jones from comment #3)

I've repeated the test and now the problem does not repeat: no timeouts and
zero "dropped" counters in the output of "netstat -ss -p ip".

The only problem is crawling copying speed (7KByte/s-14KByte/s) unless I add
mount options "rsize=10240,wsize=10240,readahead=4" to old list of options
"rw,soft,intr,mntudp", then it saturates 100Mbit/s link.
