in thread Why it takes so much time here?

Ok, what about pure CPU speed limitations?

15/100,000,000 s per iteration
= 0.00000015 s per iteration
= 150 ns per iteration

Is that unreasonable?

    I printed the time before and after the iteration, the result is both 1325041218: 

    print time . "\n";
my @a = any {$_== 92} 1..100000000;
print "\n";
print time;

    So the time is not taken by the iteration..

      oh, yes it is. 1..100000000 is executed a compile-time (constant folding).

        The same number of int takes less than 1 second to initialize

        Isn't 15 secs too much time even though a scalar requires more storage(16 bytes after test) than int?
