How to use bench mark module for sub routines in perl?

Hi,

I have 2 sub routines for example.

Code:

use Benchmark 'cmpthese';

sub explicit {
print "\n print and calculate\n";
}

sub new_per_loop {
     for (0..4){
print "\n print the loop \n";
    }
}

cmpthese (10_000, {
                 'Explicit'           => &explicit,
                 'New Array Per Loop' => &new_per_loop,
                            }
      );

It is going to an infinite loop and cmpthese function what should be the count?

What is the default count?

I tried to understand through Google but i did not get a clear picture?

In the real scenario i have to apply bench mark and calculate the time taken for a bigger sub routine which has many loops.

How can i put this bench mark to calculate the time taken by the sub routine?

If u can provide me the clear picture with an example that would be really great.

Regards
vanitha
