| The cause of this problem is my computer set time is wrong.
That should not really cause a benchmark to give incorrect results,
as the time it was set to will be correct, in the future, and the
benchmark should work then as well as now.
I suspect your problem is ...
struct timeval tm;
double t ;
static int base_sec = 0,base_usec = 0;
base_sec should be a time_t, not int, or things start to get weird from
2038 (base_sec will appear negative, so the calculation
t = (double) (tm.tv_sec-base_sec) +
((double) (tm.tv_usec-base_usec))/1.0e6 ;
will make a very large value in t (something of the order of 200 years
I suspect, though I did not calculate it) which, being intended to be
elapsed time, makes the system seem very very slow indeed.
