So I have this text file:

Bob Joe Steve
Joe Bob Mark
Joe Steve Fred
Fred Fred Joe

[download]

And I am reading and counting the names with this program:

use 5.12.4;
use strict;
use warnings;

my %wordcount;

open(FILE, "names.txt") or die "Could not open file: $!"; 

while(my $line = <FILE>) {
    chomp($line);
    my @words = split(' ', $line);
    foreach my $word(@words) {
        $wordcount{$word} += 1;
    }
}

sub hashDescend {
   $wordcount{$b} <=> $wordcount{$a};
}

foreach my $key (sort hashDescend (keys(%wordcount)) {
    print "Word: $key \t\t\t\t\t\t Count: " . ($wordcount{$key}) . "\n
+";
}

But now I want to change it up. I am going to be running this program in a huge repeating loop, so speed counts. So I want to make this faster.

I was thinking about making one big @globalarray and a @temparray and pushing from the @temparray into the global one. I am thinking this will make it a very tiny bit faster, but anything will do at this point. So how can I change my program as described, but still have the same output?
