Hello,

Should we use Thread::Queue::Any instead of Thread::Queue?

I've made a simple script to test them (see below), and the results were:

------------------------------------
TEST QUEUE:51(seconds)
------------------------------------

------------------------------------
TEST QUEUE ANY:27(seconds)
------------------------------------

I've detected a lot more of LOCKs when running Thread:Queue rather than with Thread::Queue::Any.

#!/opt/coolstack/bin/perl

use strict;

use threads ('yield',
                 'stack_size' => 64*4096,
                 'exit' => 'threads_only',
                 'stringify');

use Thread::Queue;
use Thread::Queue::Any;


my $nloaders = 16;
my $nworkers = 16;
#---------------------------------------------------------------

my $queue = Thread::Queue->new();
my $queue_any = Thread::Queue::Any->new();


my $st = time;
#----------------
# TEST QUEUE

my @thrs_loaders;
push @thrs_loaders, threads->create(\&load_hash, 0) for (1..$nloaders)
+;

my @thrs_workers;
push @thrs_workers, threads->create(\&process_hash, 0) for (1..$nworke
+rs);
$_->join for @thrs_loaders;
$queue->enqueue({'STOP' => 1}) for (1..$nworkers);
$_->join for @thrs_workers;


print "------------------------------------\n";
print "TEST QUEUE:" . (time - $st) . "(seconds)\n";
print "------------------------------------\n";

print "Enter an key to continue...\n";
<STDIN>;
$st = time;

@thrs_loaders = ();

$queue_any->enqueue(%hash) for (1..$nworkers); #

print "------------------------------------\n";
print "TEST QUEUE ANY:" . (time - $st) . "(seconds)\n";
