Data rotation in the read buffer creates latency, we know it is preset but so far its magnitude was unknown. This PR adds it as a new field to the usage struct. For example, the test_conn_echo_stress outputs now Commands sent: 780,002 Bytes sent: 32,670,085 Responses received: 780,001 Pushes received: 750,001 Bytes received (response): 3,210,147 Bytes received (push): 32,250,036 Bytes rotated: 3,109,190,184 In total approximately 34Mb are received but 3Gb are rotated.
