Problem is not in "paying the price of round-trip".  It costs nothing to
send message to file_server1 and receive it back.

Problem is that while singleton file_server is working hard on reading file
info from NFS or HDD, your request to open file on SSD is waiting in queue.
This is the problem. file module is implemented right now so that it scales
badly.
