In the self-education purposes, I want to make this quick sorting faster. Any wisdom from monks?

Perl: perl 5, version 14, subversion 2 (v5.14.2) built for x86_64-linux-gnu-thread-multi

System: Debian GNU linux AMD64

Some creepy code: 

#!/usr/bin/perl
use strict;
my (@out,$ref) = undef;
#generating some rand data
for(0..100){push @out,int (rand(300))+1;}

#Take vector ref

$ref = \@out;
sortQ(0,$#out,$ref);


#Qsort subr...
sub sortQ{
    my($s,$e,$dst)=@_;
    my$m=$s-1;
    for($s..$e-1){
        if($dst->[$_] < $dst->[$e]){
                                    $m++;
                                    ($dst->[$m],$dst->[$_])=($dst->[$_
+],$dst->[$m]);
                                 }
                }
    ++$m;

    ($dst->[$m],$dst->[$e])=($dst->[$e],$dst->[$m]);

    if($s<$m-1){sortQ($s,$m-1,$dst);}
    if($m+1<$e){sortQ($m+1,$e,$dst);}
}
