Here is the whole code...I should give it earlier

use strict;
use Devel::Size qw(size);


my $df=500000;my $tf=3;
my $wektor = '';
my $packed = '';
my $nr=0;
for(0 .. $df)
{
   vec ($wektor, $nr++, 32) = $_; # DOC ID......
   vec ($wektor, $nr++, 32) = $tf;  # TF......
   for(0 .. $tf)
   {
        vec ($wektor, $nr++, 32) = $_+10;  # POSITIONS
   }
}
print "Vector's size: " .
  size( $wektor ) . " bytes\n";



###################### UNPACK VECTOR2.....
my %vec;my %pos;
my $docID=0;
my $tf=0;
my $index=0;
my $order=1;
my $Aa=time();
for(0 .. $df)
{
        $docID = vec ($wektor, $index++, 32);
        $tf = vec ($wektor, $index++, 32);
        $vec{$docID}=$tf;
#        print "Doc id: $docID\ttf: $tf\n";
        for(0 .. $tf)
        {
            my $last=vec ($wektor, $index++, 32);
                        $pos{$docID}{$last}=$order;
        }    
}
print "unpack vector in \t",time()-$Aa,"  secs..\n";

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
