--- Comment #59 from Raymond <superquad.vortex2 at gmail.com> ---
your value are the time difference between iteration instead of time difference
between different abail


-      now_us = timespec_us(&now);
-        timestamp_us = timespec_us(&timestamp);

        if (avail1 < 0)
            break;
        if (avail != avail1) {

+           now_us = timespec_us(&now);
+           timestamp_us = timespec_us(&timestamp);


            fprintf(stderr, "now_us - last_us=%llu\t now_us - start_us=%llu\t
%llu\t Available: %d\t loop iteration: %d\n",
                (unsigned long long) (now_us - last_us),
                (unsigned long long) (now_us - start_us),
                (unsigned long long) (timestamp_us ? timestamp_us - start_us :
0),
                (int)avail1, j);
