How can I benchmarking Perl scripts

Benchmarking Perl Scripts

Benchmarking is a process to measure the performance of your Perl scripts. It helps identify bottlenecks and optimize your code for better execution speed. Below is an example of how to benchmark a Perl script effectively.


        #!/usr/bin/perl
        use strict;
        use warnings;
        use Time::HiRes qw(gettimeofday tv_interval);

        my $start_time = [gettimeofday];

        # Your Perl code here
        for (my $i = 0; $i < 1000000; $i++) {
            my $dummy = $i * $i;
        }

        my $elapsed = tv_interval($start_time);
        print "Elapsed time: $elapsed seconds\n";
