As i am just a beginer to perl programming
i dont understand the strange behaviour exhibitted by perl
My test is very simple and highly repeatable
Load file of size around 25Mb
i was shocked to see a memory usage of more than 110 Mb
Any suggestions to bring this down will be of extreme help
the code used to test it along with usage as inline comment is given below 
$| =1;
sleep(10);    # 1.5 Mb
&Test();        # 113 Mb
sleep(10);    # 108 Mb
&Test();        # 121 Mb
sleep(10);    # 108 Mb

sub Test
{
    my @l_Data;

    print "Loading\n";
    
    open(FILE,'E:\Bigfile.txt'); # Bigfile.txt is a 25 Mb File
    @l_Data = <FILE>;
    close(FILE);

    undef(@l_Data);
    print "Unloaded\n";
}

Kindly note, i must have the complete file in a array for processing,
processing it one line at a time is not helpful for my requiremnt
