Ups, your are right:
$ cat /proc/acpi/processor/CPU0/throttling
state count: 2
active state: T1
states:
T0: 00%
*T1: 50%
With T0 it get:
$ for i in `seq 5`; do ./port80; sleep 1; done
cycles: out 684, in 280
cycles: out 684, in 280
cycles: out 684, in 280
cycles: out 684, in 280
cycles: out 684, in 280
