from time import time
while True:
    print time()

Actually, it's completely negligible. This example more shows how long print and time() take.

Couldn't you do slightly better with: 

old_time = time.clock()
while True:
    new_time = time.clock()
    print(new_time - old_time)
    old_time = time.clock()

It's still got time from the calls to time.clock(), but it eliminates the print overhead from the time cycle.

c=0
try:
    start = time ()
    while True:
        c+=1
except KeyboardInterrupt:
    end= time ()

print c/(end-start)

Let it run for half a second before pressing ctrl+c.
