openssl speed benchmark test output

I have ran openssl benchmark test on my device using speed command. I am not able to properly explain what the end output is so I am confused. Here is the data

The 'numbers' are in 1000s of bytes per second processed.

Does this mean kb/s?

type             16 bytes     64 bytes    256 bytes   1024 bytes   8192 bytes
md4               1381.18k     4972.14k    14740.22k    29266.26k    41601.71k

does it mean '16 byte input, of md4, 1381.18kb of such data are executed per second'?

                  sign    verify    sign/s verify/s
rsa  512 bits 0.005364s 0.000555s    186.4   1801.6

and

                            op      op/s
160 bit ecdh (secp160r1)   0.0095s    105.5

What does these two mean?
