+vsock_perf utility
+-------------------
+'vsock_perf' is a simple tool to measure vsock performance. It works in
+sender/receiver modes: sender waits for connection at specified port,
+and after accepting it, starts data transmission to the receiver. After data
+processing is done, it prints several metrics(see below).
+
+Usage:
+# run as sender
+# listen port 1234, tx buffer size is 1MB, send of 1G data
+./vsock_perf --sender --port 1234 --buf-size 1MB --mb 1G
+
+Output:
+tx performance: A Gb/s
+
+Output explanation:
+A is calculated as "number of bytes to send" / "time in tx loop"
+
+# run as receiver
+# connect to CID 2, port 1234, rx buffer size is 1MB, peer buf is 1G, SO_RCVLOWAT is 65536
+./vsock_perf --cid 2 --port 1234 --buf-size 1MB --vsk-size 1G -so_rcvlowat 65536
+
+Output:
+rx performance: A Gb/s
+total in 'read()': B sec
+POLLIN wakeups: C
+average in 'read()': D ns
+
+Output explanation:
+A is calculated as "number of received bytes" / "time in rx loop".
+B is time, spent in 'read()' system call(excluding 'poll()')
+C is number of 'poll()' wake ups with POLLIN bit set.
+D is B / C, e.g. average amount of time, spent in single 'read()'.
