yurtesen,

in the code you gave i am wondering why a 1 sec delay wasn't used directly like:

        while (n-- > 0) {
                __asm__ __volatile__ ("rdtsc" : "=A" (t1));
                ts.tv_sec = 1;
                ts.tv_nsec = 0;
                nanosleep(&ts, NULL);
                __asm__ __volatile__ ("rdtsc" : "=A" (t2));
                printf("%llu\n", t2 - t1);
        }

any idea?
