Hi i have a below program to compare two file and log the result in new file. Its taking more than 10 min to log the data to AuditNew.txt file. br.1 file have around 3 lakh lines and MSMLogs.txt will have around 7,000 line.

Is there is any way to get the result logged faster in AuditNew.txt.

Note : Below print is displayed in console every 1 seconds for each line. it means the processing is faster but writing the data to text file is getting delayed. 

print("\nnumber of occurance is $count\n");

#!/usr/bin/perl

use 5.010;
use strict;
use warnings;

#Open MSM Log in read Mode
open(my $MSMLog, '<','MSMLogs.txt');

#Create Audit txt file in write mode
open(my $Audit, '>','br.1');

print("Task Started.........\n");
#iterate each word to identify the logs
while (my $row = <$MSMLog>) {
  chomp $row;
  getCount($row);
}

sub getCount {
  #Open MobileService.log file in read mode
  open(my $MobileServiceLog, '<','one.txt');
  my @StaticLog = @_;
  my $count = 0;
  #print ("\nvalue in MSM Static is ------ $StaticLog[0]\n");
  
  while (my $row = <$MobileServiceLog>) {

    my @actualWord = split /;/, $row;
    my $MobileService = $actualWord[7];
    #print ("value in MobileService is ------  $MobileService\n");
    if ($MobileService =~ /$StaticLog[0]/) {
        $count += 1;
      }
  }
  $_=1
  print ($Audit "\n$StaticLog[0] occurance is ------- \t$count\n");
  
  print("\nnumber of occurance is $count\n");
  close $MobileServiceLog;
}
print ($Audit "Task Completed");
print ("Task Completed");
close $MSMLog;
close $Audit;
