I am trying to output the hash to a file "hash_glf.txt",using the following code,the file given as input is 40,000 lines.It takes a lot of time to outpuf to "hash_glf.txt",if I change the input file to some 100 lines,I can see the hash structure being output'ed to hash_glf.txt immediately.Is there a way I can quicken the script to output to the file quickly? 

#!/usr/bin/perl -w 
use strict;  
use warnings;  
use Data::Dumper;
my %files_by;
print "Enter File1 ";  
my $file1_name = <>;  
chomp($file1_name);
open my $DATA, '<', $file1_name or die "Cannot open file 1\n";
 
while (<$DATA>) {
    my ($file_path, $file_name, $version)
        = m{^(.*/(.*))#(\d+)$};

    push @{ $files_by{$file_name} }, {
        file_path => $file_path,
        version   => $version,
    };
}


open my $hash_glf, '>', "hash_glf.txt";
print $hash_glf Dumper( \%files_by );
close $DATA;
