    Note that it is part of the perl core (as of perl5.003_07).

    It does just what you want, ie. allows you to compare the execution times of different approaches.

    use Benchmark; 
my $t0 = new Benchmark; 

# See code run 

my $t1 = new Benchmark; 
my $td = timediff($t1, $t0); 
print timestr($td) . "\n";

    Use as many or as few of those Benchmark objects as you'd like at any point in the program. The CPAN docs on Benchmark are great, but I thought it may be helpful to see the code right here. Instant gratification is key. :)

        Benchmark -- It's its own module -- in the standard Perl distrib.
