I write a code normally and its taking 186 wall clocks to read the total files. To reduce the time I created process and split my load for two process. After creating process its taking 261 wall clock seconds. What's the mistake I am doing?? I think by creating process and running it parallel may reduce the execution time. But its increased. How??? 


sub SMSBcastCDR 
{
       #doing operation on files
}

sub SMSCDR
{
     #doing operation on files
}

LINKS:
foreach my $linkarray (1 .. 2) 
{
    $pm->start and next LINKS; # do the fork
    
    if ($first == 1)
    {
        my @cdr_list1 = `ls $cdr_directory/SMSBcastCDR_*_$bcat_cdrdate
+\_*.log`;
        print "cdrs_file1 = @cdr_list1\n";
        SMSBcastCDR(@cdr_list1);
        $first++;
    }
    if ($first == 2)
    {
                my @smsc_cdr_list=`ls $smscdr_directory/SMSCDR_P*_$cdr
+date*.log`;
        SMSCDR(@smsc_cdr_list);
    }
    $pm->finish; # do the exit in the child process
}
$pm->wait_all_children;
