The time command prints how much time was required by the application.
If you divide that with the elapsed time you have the CPU load of the
application. The number of packets is irrelevant and the cpu must not
be limiting; if it is the application will not run in real time and
the measurement will be incorrect.

In a terminal you type:
time rtl_fm
with the rtl_fm parameters you want to use. When you stop the program
it will print out how much real time has passed and how much time was
used by the application. See "man time" for options.
Not the best way, unless you print #of packets processed and cpu is
limiting. A better choice would be gprof (Linux).
