It is common to use gettimeofday(2) to measurethe performance of a code segment under study,similar to the following: struct timeval start, end;
If the code segment executes in only 1 microsecond, describe two ways that you can prevent the execution cost of calling gettimeofday from interfering with your measurements
The ?rst way is to use clock_gettime(2), but this approach only works if your system supports nanosecond resolution for its timers. The second way is to execute the code to be measured multiple times to amortize the cost of callinggettimeofdayacross all iterations, and then report the average time for a single iteration.
