Hi All,

I am developing a Log processing tool.Thought Perl would provide me the best solution for text processing as compared to Java.

Here is my question,

I have a Hash map containing 100 key/value pairs.

Need to parse a huge file containing some 65000 lines, compare each line against a value of the Hash map and find the key if the value matches with the line.
Code snippet as follows,

$start = time();
TEST1: while (<FILEHANDLE>){
        $count = 0;
    
    foreach  $value5(values %msgDefn) {
            $count ++;

          if ($_ =~/($value5)/){

              print "Match found in $count iterations";
              print  $_;
              next TEST1;
         }
         
       }
       
}
$end = time();
print "Time taken was ", ($end - $start), " seconds";

It takes at an average of 30 seconds for file

.I need to do it in a optimized way , since parsing thousands of similar file would take hours for processing.

Is there anyway using mechanisms the processing time can be reduced.

Thanks a lot.
