Latency typical: 0.717812 usec
Latency best : 0.705625 usec
Latency typical: 1149 cycles
Latency best : 1129.5 cycles
after modifying the per usec cycles
the results are:
Latency typical: 5.76884 usec
Latency best : 5.66834 usec
gettimeofday() results are:
Latency typical: 6.000000 usec
Latency best : 5.500000 usec
